Mozilla recently unveiled the llaunch of the new version of Firefox 94, in which this update of your browser introduces six "seasonal colors" (themes) that will be only for a limited time in the browser.
Another of the changes that stands out in this new version is the tab download is a feature built into Firefox since version 93 for windows that helps reduce memory usage when downloading tabs that you are not actively using. To avoid crashes, Firefox will automatically select and download these open tabs when system memory is low. This is a smart process that avoids downloading tabs that play media, using Picture-in-Picture or WebRTC.
In Windows, Out of Memory (OOM) situations are responsible for a significant number of browser crashes and content processes reported by users. Downloading tabs saves Firefox memory, reducing crashes and avoiding interruptions associated with using the browser.
Mozilla believes this can be especially beneficial for people who do heavy browsing work with many tabs on machines with limited resources. Or maybe these users are simply trying to play a memory-intensive game or are using a website that is getting a little resource-hungry. And, of course, there are the eyelash hoarders. Firefox is now better at surviving these situations.
When the system memory is extremely low, Firefox will start downloading tabs automatically. Downloading tabs could interrupt users' browsing sessions. Hence, the approach aims to download tabs only when necessary to avoid crashes. On Windows, Firefox receives a notification from the operating system (setting using CreateMemoryResourceNotification) indicating that the available physical memory is low.
Moreover Firefox macOS now uses Apple's low-power mode for full screen videos on sites like YouTube and Twitch. This dramatically prolongs battery life during long viewing sessions.
Whereas in Windows, there will now be fewer interruptions, since Firefox offers you an option that, once activated, will no longer ask you to perform updates. Instead, a background agent will download and install updates even if Firefox is closed.
On Linux, Mozilla has improved the performance of WebGL and has reduced power consumption for many users.
Also, to better protect all users from Firefox against side channel attacks like Specter, Site Isolation is now available for all desktop platforms.
Site Isolation is based on a new security architecture that extends protection mechanisms current by separating the content (web) and loading each site in its own operating system process. This new security architecture allows Firefox to completely separate the code from different sites and, in turn, defend itself against malicious sites that try to access confidential information from within.
As a first line of defense, Firefox applies a variety of security mechanisms, for example the same-origin policy, which prevents access to confidential information, such as your password or credit card number, when it is loaded into the same application.
