Google Chrome is an Internet browser based on the WebKit engine developed by Google based on the free Chromium browser. It was first shown to the public on September 2, 2008, while the stable release took place on December 11, 2008. It should be noted that at the same time dev and beta versions were available for Linux and Mac OS X operating systems. Development was carried out by former employees of the Mozilla Foundation. At the moment it ranks first in the world in terms of popularity.
According to Google, their browser was created with the expectation of improving the speed, stability, and security of Internet surfing. Also in 2009, the developers outlined a strategy for the development of Chrome. It consists in providing minimal functionality (which can be expanded with plugins)and maximum speed.
As for security, the browser regularly downloads updates from several blacklists of malicious and phishing sites, warning users if they try to visit them.
Unlike other browsers, Chrome uses a multiprocessor architecture and creates a separate process for each tab (process isolation) to prevent them from interacting. This is also useful if a tab freezes when processing content: it can be "killed" without losing information in others. Each tab, in fact, is located in a separate sandbox (read and write are forbidden). An attacker who gets information from one tab will not be able to view the other tabs.
Chrome also has a task manager that allows you to view the usage of the user's processor, RAM, and Internet channel by sites and plug-ins, and terminate them if necessary.
Previously, the popular Adobe Flash Player plugin was not part of the browser and was not built into the sandbox. However, starting with version 5.0.375.86, it has been integrated.
To prevent malicious software from downloading to your computer, a mandatory function was introduced to confirm saving files with .exe, .dll, .bat extensions.
Chrome supports incognito mode, similar to the private mode in Firefox: the pages you view do not appear in your browsing and search history, and cookies are not left – they are automatically deleted after you close the tab. This does not apply to downloaded files.
However, this mode does not allow you to protect yourself from certain things:
- from websites that collect information about users;
- from malicious software, in particular, keyboard interceptors;
- from surveillance and viewing by special services.
The main interface element is the tab bar located at the top of the window. Tabs are easily swapped, and can also be moved to a free window. Each of them has its own set of elements, including an Omnibox field that combines a search bar and an address bar. If an address doesn't match the URL spelling rule, Omnibox automatically redirects it to the Google search engine. Chrome also allows you to place local shortcuts on apps (for example, you can download the game Angry Birds for free and run it directly in the browser).
The main criticism is directed at the function of collecting statistics of sites visited by the user.
