blacklist
Chrome will regularly download and update two blacklists (to prevent phishing and malware) and warn users when they try to browse websites that may cause computer damage. Use other free APIs) "Google Safe Browsing API" can also get this service. While updating and maintaining these blacklists, Google will also notify the listed websites, so as to prevent the website holders from not knowing that the websites contain malicious software [7].
sandbox
Every tab in Chrome is a sandbox to "prevent malware from installing itself" or "use one page to influence other pages". Abide by the principle of least privilege, the privilege of each processing action will be restricted, and you can only calculate that you can't write files or read files from sensitive areas (such as my documents and desktop). This function is similar to the "protected mode" of Internet Explorer 7 on Windows Vista. The "Sandbox Team" said that they "used the existing execution procedure restrictions and turned them into prisons". For example, malware running on one of the tabs will not be able to steal the credit card number, interfere with mouse operation, or tell the system to execute a program at startup. When the tab is closed, the malware will stop immediately. This function provides a simple computer security mode, in which there are only two security levels (user and sandbox), and the sandbox will only respond to the user's instructions [7].
plug-in component
Plug-ins such as Adobe Flash Player usually have no uniform standard and cannot be sandboxed like tab. These usually need to be performed at the browser itself or at a higher security level. In order to reduce the risk of being attacked, plug-ins are executed in different handlers. [7]
Anonymous; In anonymity
Chrome includes "anonymous" mode (similar to Safari's "private browsing" and Internet Explorer 8), which can "let you browse the web in complete privacy because your activities will not be recorded" and will not save cookies. When this feature is enabled in a window, "nothing that happens in this window will enter your computer." [ 1]
disadvantaged
The Xxx plug-in will crash when used.
Using VISTA as the default browser, other programs accuse you of making mistakes when opening web pages.
Self-proclaimed multi-tab browsing, in fact, every tab page opened will increase the chrome.exe memory occupation by 40-60MB. "[2]

Java Script language
Use the built-in independent JavaScript virtual machine "V8" to improve the speed of running JavaScript.
Google browser speed
stability
Multiple processing
It can allow multiple programs to execute at the same time without affecting each other, and each web page label will exist separately at the outer edge of the program window. When resources are too high or crash, the whole program will not be suspended because of suspension.
Task manager
Please check in the "Other Knowledge" directory.
User Interface(UI)
gear
Chrome includes Google Gears, which allows developers to make web applications (including offline support) [7].
New tab
Chrome uses a "new tab" instead of the home page that other browsers will load when they open a new tab. The new tab shows the thumbnails of the nine websites visited recently, as well as the most frequently searched websites, recent bookmarks and recently closed pages [9].
Multifunctional address bar (Omnibox)
At the top of each tab, there is an address bar named "Omnibox", which is based on the address bar on Opera. Omnibox has the function of automatic completion, but it will only be effective for manually entered URLs; In addition, there are search suggestions, last visited pages, popular pages (not visited) and search records. [7]
Pop up window
The pop-up window will be displayed in the tab and will not appear outside the tab unless the user drags the window to another place. [7]
Kernel engine
The browser is developed based on the kernel engine of WebKit open source project.
The predecessor of WebKit is KHTML of KDE Group. Apple carried forward KHTML and launched Safari, a browser with improved WebKit engine based on KHTML, which received a very good response.
At the suggestion of the Android team, Chrome uses the WebKit kernel engine. WebKit is very simple and can use memory efficiently, so it is quite easy for new developers to get started. [7]
tabs
Tab is the most important element in the Chrome user interface, which is located at the top of the window rather than at the bottom of the menu (similar to Opera). This change is different from many tabbed browsers at present. Tab pages in different windows can be easily switched by dragging. Each tab has its own toolbar, including an address bar called "Omnibox".
Web applications (Webapps)
Web applications can run in Chrome without Omnibox and browsing toolbar.
Seven reasons why Chrome is popular.
1, will not crash.
Chrome's biggest highlight is its multi-process architecture, which protects the browser from crashing due to malicious web pages and applications. Every tab, window and plug-in runs in its own environment, so problems in one site will not affect other open sites. This architecture further improves the security of the system by limiting each site and application software to a closed environment.
2, the speed is quite fast
Due to the multi-process architecture, the slow loading speed of one site will not drag down the access to other sites. Users can easily click on other tabs or windows. The same is true for plug-ins. For example, if a website opened by a user contains slow-loading Java advertisements, the Java code itself will be isolated and the rest of the webpage will not be affected. After clicking the icon, Chrome can start in a few seconds-far ahead of some competitors.
3. Almost completely invisible
It is not enough to say that the interface of Chrome is simple. Chrome is hardly like an application, a screen.
Google Chrome
Most of the screen space is used to display the websites visited by users, and the buttons and logos of Chrome will not be displayed on the screen. Chrome designers say they want users to forget that they are using a browser software. Their goal has been basically achieved.
4. Search is easier.
One of the iconic features of Chrome is Omnibox, a universal toolbar located at the top of the browser. Users can enter the website address, search keywords or both in Omnibox, and Chrome will automatically perform the desired operation. Omnibox can understand users' preferences. For example, if a user likes to use the search function of the PCWorld website, once the user visits the website, Chrome will remember that the PCWorld website has its own search box and let the user choose whether to use the search function of the website. If the user chooses to use the search function of the PCWorld website, the system will automatically perform the search operation.
5. Users will have more control over labels.
Chrome provides a new function of tabbed browsing. Users can "grab" a label and drag it into a separate window. Users can integrate multiple tabs in one window. Chrome can use the configuration of a tag that users like at startup, and other browsers need third-party plug-ins to provide this function. It is generally estimated that Google Chrome is an important strategic measure for Google to expand its control over the Internet. Google
Google Chrome
While supporting Mozilla Firefox, the company develops its own Google Chrome browser, which will have a far-reaching and fatal blow to the ie browser that Microsoft still dominates. Moreover, with the development of network-based software, the new browser is likely to realize the similar functions of Google operating system that many people expect, thus replacing Microsoft's dominant position in personal computers. Google launched a browser for users to download and launched a new "war" with Microsoft.
In addition, Google Blogoscoped, a famous technology blog headquartered in Germany, published a cartoon, the content of which is obviously an explanation of the technical problems of the new browser. According to sources, Google's open source browser is called "Chrome". Prior to this, the struggle between Google and Microsoft was more like a "cold war", mostly limited to Google developing small, web-based software and competing with Microsoft's leading products such as Word and PowerPoint. Microsoft has been trying to break Google's monopoly position in the search market, but it has not been successful so far.
But Google's move will make the war between the two more intense. Various surveys show that Microsoft's share in the browser market is about 3/4, and Google is trying to grab a considerable part of it. Inside Google, rumors about the launch of the browser have been around for a long time, but no one knows when it will be released.
Obviously, Google sent the above comics to Google for printing through FedEx, and perhaps sent them to others. The following is the content of this cartoon:
According to sources, Google plans to launch its own browser because it is worried that the new features of Microsoft IE8 may be detrimental to its search business, including privacy and a more Microsoft-centric search bar. The former may prevent Google from collecting relevant information such as the effectiveness of its advertisements.
In recent years, Google has been supporting Mozilla's Firefox browser to challenge the dominant position of Microsoft IE. The latter was reborn from the once powerful Netscape browser, and its market share quickly reached an astonishing 18%, Microsoft IE 74%, and Apple Safari 6%. In just two years, the market share of Firefox is only 1 1%. Mozilla6 launched Firefox 3 in mid-June, with 8.3 million downloads within 24 hours after its release.
Last week, Google extended its search contract with Mozilla to 20 10 to get permanent configuration on Firefox, including default home page and default selection of search bar. Since then, Google has paid Mozilla a sum of money for advertising clicks on Firefox search.
But obviously, it is not enough for Google to renew Mozilla's contract. Google has obviously decided that it must own or distribute its own browser, especially when it becomes the largest company in the network-related software industry.
In other words, Microsoft will take the browser as its main product in the future, and this strategy is completely correct.
On September 2, 2008, the Wall Street Journal quoted an unnamed source as saying that Google planned to launch its own web browser called "GoogleChrome" in an attempt to challenge Microsoft IE's dominance in the browser market.
The newspaper also said that Google's browser will be listed in a short time.
The Wall Street Journal reported that the "Google Chrome" browser was originally developed to improve the speed of web browsing and make it easier for users to browse the web. In addition to providing an enhanced address bar, it also adds many new functions that are completely different from other browsers. In addition, browser products will implement an open source strategy, which means that other developers can modify the source code.
Google did not respond to relevant phone calls and e-mail inquiries in time.
Google has been engaged in browser research and development for more than two years, but since Microsoft released IE7, Google's browser research and development work has become more mysterious, with little information disclosed.

Google browser and high speed
Browser can speed up in many aspects, and Google browser pursues all-round speed and responsiveness.
quick start
After double-clicking the Google Browser icon, Google Browser will start from the desktop in a few seconds.
Quickly load web pages
Google browser is strongly driven by WebKit open source rendering engine, which can load web pages in real time.
Run network applications quickly.
As far as the internal mechanism is concerned, Google browser is equipped with V8, which is a more powerful JavaScript engine that we built to run complex network applications at high speed.
In each new version, Google browser is committed to improving JavaScript performance.
Because the network applications we use every day are more and more dynamic, it requires the browser to quickly build and change the elements on the web page in the shortest possible time. Mozilla's Dromeao DOM core test detected this function. Like JavaScript performance, Google browser is constantly improving the core performance score of each new version of DOM.
Quick search and navigation
Google Browser combines a search bar with an address bar (called a "multi-function box"), where you can enter search terms and network addresses.
The multi-function box can provide suggestions for searching words and network addresses according to your input, and its auto-completion function allows you to find what you are looking for with just a few keys.
Google browser and browser security
Google Browser contains a series of functions that can help you and your computer to avoid attacks from malicious websites when browsing the Internet. Google Browser will use technologies such as secure browsing, sandbox and automatic update to help you resist online deception and malware attacks.
Edit this paragraph
Secure browsing
Google browser will send you a warning message before you enter a website that may contain malware or online fraud.
Online spoofing attack refers to the behavior of someone impersonating others to defraud your personal information or other sensitive information, usually in the form of fake websites. On the other hand, malware refers to software that is automatically installed on your machine without your knowledge. The purpose of these softwares is to damage your computer or steal information from it.
After enabling secure browsing technology in Google Browser, when you encounter a website that may contain online deception or malware while browsing the network, you will see a warning page similar to the following.

sandbox
Sandboxing helps prevent malware from installing itself on your computer or using activities in one browser tab to influence activities in another. Sandbox can prevent malicious web pages from installing programs on your computer, monitoring your network activities or stealing private information from your hard disk, thus adding an extra layer of protection to your browser.
Edit this paragraph
autoupdate
To ensure that your computer can be protected by the latest security updates, Google Browser will regularly check for updates to ensure that the latest version is always used. Checking for updates ensures that your version of Google Browser will automatically update the latest security features and fixes without your taking any action.
Browser, Google browser, privacy and you
The purpose of building Google Browser is not only to improve the speed, but also to protect your online shared information and let you control your private information.

privacy protection
1. stealth mode
If you don't want to record the websites you visited or downloaded in the browsing history and downloading history, you can browse in stealth mode. In fact, this is a very convenient function that can help you prepare surprise gifts and birthday parties! In addition, when you close the hidden window, all Cookie created when browsing the web in hidden mode will be deleted.
When browsing the web in stealth mode, you will see the stealth icon in the upper right corner of the browser.
Hiding mode is particularly convenient because it allows you to easily browse the web secretly without having to change the privacy settings repeatedly between browsing sessions. For example, when you open a regular session, you can open an invisible session in another window.
2. Privacy preference
You can control the privacy preferences of all Google browsers in the Privacy section (located at the top of the Advanced Settings tab in the Options dialog box).
3. Clear browsing data
When using Google Browser, you can clear the browsing data at any time to prevent it from being stored in the browser. You can completely control the types of browsing data to be deleted in the browser, including browsing history and download history, Cookie, saved passwords and saved form data. 4. Control the privacy preferences of cookies, pictures, JavaScript and plug-ins. In the content settings of Google browser, you can control the privacy preferences of cookies, pictures, JavaScript and plug-ins of each website respectively. For example, you can set Cookie rules to allow only cookies from a list of specific websites that you trust, and instruct Google Browser to block cookies from all other websites or apply for permission first.

Related defects
Google Chrome is a popular browser, but unlike other competitors such as Firefox, Opera, Safari and Internet Explorer, this browser seems unable to automatically detect RSS feeds so far. When you open RSS directly with a browser, the text code will be displayed. Unless a bookmark manager is added to this address, it will not be friendly to read. This function, which is very easy to realize but not provided, has attracted the attention of technical enthusiasts.
Google explained this today, originally intended to use RSS as the default support function (not excluding future support), but in the end they decided to leave this function of identifying RSS to readers for extension.
The reason for this setting is that Google thinks it is more important to allow each user to customize their own browser, and the function of automatically identifying RSS feeds may bring trouble to some people.
It is undeniable that the speed and security performance of Google Chrome browser are unparalleled; However, Google Chrome browser has an obvious disadvantage: the address bar is too long and useless, which wastes a lot of space, instead of adopting the classic mode of adding a search engine box to the address bar, which greatly reduces the user's usability;
Google Chrome browser, and some other browsers are not satisfactory, such as:
The 1 label is the link bar of IE6.0 browser. I believe it is the most used by most IE6.0 browser users. It is convenient for everyone to drag commonly used websites from the address bar to the quick link bar. Now many browsers use tags instead. A big problem is the horizontal display, which not only occupies a column in vain and sacrifices the display space of the webpage, but also cannot be displayed completely at a glance. In the end, the horizontal screen depends on the vertical screen, which is self-defeating and thankless.
2 Search in the site Many browsers have adopted the classic style of adding a search engine to the address bar, which is really convenient and easy to use. However, the browser search engine basically does not provide the basic choice of on-site search. Just opened a website, there will definitely be a search box on this website, which is disappointing, and various search engines rarely provide on-site search options, which can be described as collective blindness;
With the rapid development of network, the gap of software performance is narrowing, and user experience has become the key to the survival of the fittest in the market. A beautiful skin, at the expense of a little memory, gives users a good mood. After all, surfing the internet is for happiness; At this point, Google Chrome browser is not satisfactory, users with too few choices, too slow updates and less freedom cannot make their own websites;
4 Browser Upgrading Google Chrome browser is just like Google Toolbar. Forcing users to upgrade is an important reason why many users abandon it. Many users are worried that the endless automatic upgrade will affect computer performance. At present, the browser function has met the demand, and many people can't master the upgrade freely to improve the system performance and reduce the resource occupation, which makes people speechless.
