Security

Chromium periodically updates download black (one for phishing and one for malicious software), and warns users when you visit a site "malicious". This service is also available for use by others through a free public API called "Google Safe Browsing." Google warns owners of the premises referred to may not be aware of the presence of malicious software [9].

Chromium usually assigned to each card suits in their process of "preventing the installation of malicious software from the same" or "using what happens in a card to influence what happens in the other, but the same process model is more complex. [27] Following the principle of least privilege, every process is stripped of his rights and can count, but can not write or read files from sensitive areas (such as documents, desktop)-This is similar to the "protected mode" used by Internet Explorer 7 on Windows Vista. Sandbox The group is that they are "taking the current process and made it marginally in a prison" [28] For example, malicious software running on a card is able to smell Credit card numbers, interact with the mouse, or to say "Windows to run an executable to start" and stops when the card is closed. This requires a simple model of computer security where there are two levels of multilevel security (and user sandbox) sandbox and can only respond to requests from the Commission initiated the user [29].

Usually, Plugin, such as Adobe Flash Player are not standardized and, as such, can not be sandbox as the cards may be. They often operate at or above the level of security of the browser itself. To reduce exposure to attack, the plug-in running in separate procedures for communicating with the renderer, the same as those working in "very low privileges" in each card dedicated processes. Plugin should be modified to operate within this architecture software, and in accordance with the principle of least privilege [9]. chromed supports Netscape Add Application Programming Interface (NPAPI), [30] [31], but does not support the integration of the ActiveX control [31]. In addition, Chrome has Like any system extension Mozilla XPInstall architecture [32]. Applet Java support is available as part of chromium 6 in Java pending update 10, which is now in Release Candidate test [33].

A private browsing feature called incognito mode is a condition that prevents the browser from storing information or any history of cookies from sites visited. This is similar to private browsing feature available on Apple Safari and the latest beta version of Internet Explorer 8 [34].

A Denial of Service vulnerability has been found that allowed a malicious website to crash the entire web browser. [35] [36] However, developers of Google chrome confirmed the problem, and this was set to release 0.2.149.29. [37]

Speed

The JavaScript virtual machine was considered sufficiently important work that must be removed (such as Adobe / Mozilla Tamarin is) and managed by a separate group in Denmark. Existing applications designed for small projects, where performance and interactivity of the system that was not important ", but web applications like Gmail" is using the web browser to the most when it comes to JavaScript and DOM manipulation " . The resulting JavaScript V8 engine has features such as hidden for transitions, the dynamic generation of code, garbage collection and accurate [9]. Tests by Google revealed that V8 was about two times faster than Firefox and Safari 3 beta 4 [38].

Several websites reference tests are conducted using the SunSpider JavaScript Benchmark [1] tool, Google and its calculations intense series of benchmarks, which include monitoring and pressure-ray resolution. [39] The report unanimously that the chromium is running much faster than all its competitors in which the system was tested, including Safari, Firefox 3, Internet Explorer 7 and Internet Explorer 8. [40] [41] [42] [43] While the opera has nothing to do with Chrome also, in previous studies, has proven to be slightly slower than Firefox 3, which in turn is slower than chrome. [44] [45] Another Mozilla developer blog Brendan Eich chrome comparison to its V8 engine TraceMonkey Javascript engine was recently introduced in Firefox 3.1alpha, saying that some tests are faster with an engine and some are faster than otherwise, with overall faster than Firefox 3.1a. [46] John Resig, Mozilla evangelist JavaScript, further comments on the performance of the various browsers for the same suite of Google, the discovery of Chrome "decimating" other browser, but wonders if the Google suite is representative of the actual programs. Firefox declares that the pay in intensive reference, such as Google, as the Mozilla team has not been implemented yet back-tracking [47].

Chromium prefetching also uses DNS to speed up searches web site [48].

Stability

The team examines a browser Gears multithreaded (note that a problem with the current implementations of web browser that is inherently single threaded) and Chromium apply this concept to a multi-architecture, [49] similar loosely affiliated with Internet Explorer ( LCIE) Dove recently implemented by Internet Explorer 8. [50] By default, is a special procedure available for each site and thanks plugin. [51] This prevents tasks from interfering with one another, which is good for security and stability; Success an attacker to access an application would have access to all, a failure in one Sad application results in tab screen of death, similar to the known Sad Mac, with the exception of a single sheet hangs instead of the entire application. This strategy exacts a fixed cost for each process forward, but leads to overall inflation of less memory fragmentation as limited to any process and does not entail additional memory allocations [52].

Chromium is characterized by a process management utility called "Task Manager that allows the user to" see what sites using more memory, more downloading and abuse of byte [their] CPU "(as plugins that operate in separate processes) and a fine them. [9] Some users have reported a conflict with Internet Explorer, often result in a blue screen error Windows [53].

User
When Chromium increases, the title bar is hidden and instead, the tab bar appears at the top. Also, when you move the mouse over a link, the URI of the link appears in a row on the lower left. Otherwise, the line is invisible.

When not maximize Chrome, the title bar appears at the top of the tab bar.
When not maximize Chrome, the title bar appears at the top of the tab bar.

The main users include backward, forward, refresh, bookmark, go and cancel the options. The options are similar to Safari, while the position of the system are similar to versions of Internet Explorer from version 7. The design of the window based on Windows Vista.

When the window is not maximized, the tab appears immediately below the title bar. When maximized, the title bar disappears, but the tab bar appears at the top of the window. Unlike other browsers like Internet Explorer or Firefox, which should also be full-screen mode that hides the operating system interface completely, Chromium can be maximized only as a formal application for Windows. Therefore, the Windows taskbar, the system tray, and Start Menu link yet, in any case, if they are not configured to hide at all times.

Chrome includes tools, adds functionality to developers usually associated with the construction of Web applications (including support offline) [9].

Chromium replaces the browser start page that appears when a new tab is created with a new page. This shows [54] preview of nine sites visited along with the positions searched more frequently in recent bookmarks, and recently closed tabs [9].

The Omnibox is the URL box at the top of each card, which combines the functions of both search and URL position. Includes automatic features, but only automatic URL you have entered manually (and not all links), suggested searches, pages higher (visit), popular pages (unvisited), and text search of history. Search engines can also be caught by the browser when used by indigenous user pressing Tab [9].

The pop-up "is the range of card that came from" and will not be shown outside of the card if the user did not explicitly draw them. [9] pop-up windows not performed in their own process. [Change]

Chrome uses the WebKit rendering engine to display Web pages on advice from the group of cyborg. [9] Like most browsers, Chrome has been widely tested within the unit before the release of the audit, the 'automated test user actions user reads "Fuzz as well as inspection and testing of the device WebKit ( 99% of chromium that has claimed to have exceeded). New based browser automatically tested by tens of thousands of public access to web sites through the Google index within 20-30 minutes [9].

The cards are the main user of Chromium and, as such, have moved to the top of the window and not under control. This subtle change is in contrast with many existing browsers are cards, which are based on Windows and contains cards. Cards (including the state) can be transferred smoothly between the window with container transport. Each tab has its own control, including Omnibox [9].

Chromium allows users to the local desktop connections that open applications in Web browser. The browser, when it opened in this way, does not contain regular interface apart from the title bar, so as not to "interrupt whatever you are trying to do." This allows web applications to run in parallel with the local software (like Mozilla Prism and liquid) [9].

By default, the line is hidden when not in use. However, it appears in the lower left every time you load a page when a hyperlink has fluctuated over.

For Web developers, Chrome features of a component, the inspector similar to Firefox.
