The new version of Firefox 86 has already been released and introduces total protection against cookies

Firefox Logo

Mozilla released Few days ago the launch of the new version 86 of the Firefox browser which comes with various improvements, bug fixes and especially some new functions.

Of all the new features that are introduced, the biggest change refers to privacy and data protection. Mozilla has incorporated a feature that should make it impossible for cookies to track users.

Regarding cookies, Mozilla had already implemented other functionality in version 85 from your browser. Firefox 85 was released with a super cookie protection layer to prevent hidden trackers from tracking Firefox users' activity while browsing the internet. 

This mode of isolationo does not allow the use of cookies to track movement between sitesas all cookies set from third-party blocks uploaded to the site are now linked to the main site and are not transmitted when these blocks are accessed from other sites. As an exception, the ability for cross-site cookies is left for services not related to user tracking, for example, used for single authentication.

Another novelty that is presented in this new version of Firefox 86 is the ability to view multiple videos at once in picture-in-picture mode. Before version 86, trying to watch another video automatically separated the first one.

On the other hand, it stands out that a new interface has been activated to preview a document before printing for all users and integration with printer system configuration has been provided.

The new interface works by analogy with the reader mode and leads to the opening of a preview in the current tab, replacing the existing content. The sidebar provides tools for selecting a printer, adjusting the page layout, changing print settings, and controlling whether headers and backgrounds are printed.

We can also find that rendering operations for Canvas and WebGL elements have been moved to a separate process responsible for outsourcing operations to the GPU. The change significantly improved the stability and performance of sites that use WebGL and Canvas.

In addition to the innovations in Firefox 86, 25 vulnerabilities have been corrected, of which 18 are marked as dangerous, 15 vulnerabilities (compiled for CVE-2021-23979 and CVE-2021-23978) are caused by memory problems, such as buffer overflows and access to already freed memory areas. These problems could potentially lead to the execution of attacking code when opening specially crafted pages.

Finally, it should be mentioned that in the beta version of Firefox 87 the power to disable the backspace key driver is highlighted default outside the context of input forms. The removal of the handler is explained by the fact that the Backspace key is actively used when writing forms, but if the input form is out of focus, it is treated as if it went to the previous page, which can lead to loss of typed text due to to involuntary movement to another page.

How to install the new version of Firefox 85 on Linux?

    Well, if all that is very cool, but it would be better for them to work on the speed of it. Then they complain that they have to fire people who do not have money, etc. Firefox has been with us for a lot of years for it to have improved in that aspect, what do I mean? It's simple, in any Linux distro, because I only use Linux and I have tried them all. I use xfce and I like to have the icons in the taskbar with a single mouse click. Well, I just click on the Chrome icon and it instantly opens and with Firefox, no, I give it and I have to wait for it to open, yes, it's only a few seconds, but I have to wait and with Chrome it's instantaneous, like after the navigation that is much faster with Chrome. Yes, Chrome will spy on me, so let him spy on me, I will gladly in exchange for what it offers me, speed like lightning. With the years that Firefox has been, it is so that they were on par in terms of speed and surely if they had worried about that, they would be above Chrome in terms of market use. The problem with Firefox is that they have never managed to manage what they have in their hands. Firefox already existed when Chrome came out, and why did Chrome rise like foam and practically since it came out it became the most used browser in the world and still is? Easy, because of the speed. So you already exist and a new browser suddenly comes and ranks first in the world for being the fastest and you don't do anything? Well that.
