Google Chrome secretly activates a feature called Site Isolation

Chrome includes a function that allows web pages not to know the contents of other tabs opened by the user.

The name of the function is Site Isolation and the main objective is to avoid that in computers vulnerable to Meltdown and Specter you can spy on the contents of Chrome tabs.

Now this feature has been enabled in almost all browsers Windows, Mac, Linux and Chrome OS users.

The function arrived at the browser with Chrome 63, but it was necessary to manually activate a flag to make it work. Thus, the act of activating it in secret is particularly curious, since this function completely changes its operation

Now, what does Chrome create a different browser process for each Domain Internet, explains the América Retail website.

Initially, this function was somewhat long term, but Google made it a priority to protect itself from the attacks of Meltdown and Specter when they were released in January.

The caution with which Google launched the function has to do with the fact that they have been monitoring the performance of the browser in computers, since the execution of several processes consumes up to At 13% more RAM according to Google

This higher consumption offsets the increase in security according to the engineers of the company.

Isolation Site will soon be mobile Android . The function can be activated manually via chrome: // flags / # enable-site-per-process

The engineers claim that it will also allow them to eliminate some of the attenuations of Meltdown and Specter who added to the browser, which also affected the performance . These are no longer necessary, so the final decrease is compensated.

One of them is the SharedArrayBuffer, which has disabled other browsers such as Firefox or Edge to protect against vulnerabilities.

This will allow developers to create more accurate Web applications that can handle real-time data more easily.
