Manual unloading of tabs for more stabilityįirefox on Windows has been able to automatically unload tabs and thus free up RAM in situations in which the available memory is running low since version 93. According to the plan, the rollout should be completed for all users by Firefox 96. With Firefox 94, Mozilla Fission is gradually rolling out for the first users.
On the other hand, a single tab can also require several processes, namely when frames from other domains are embedded on the page. two tabs from the same domain can share a process. It would be more precise to say that there is one process per origin, i.e. Put simply, this means that each tab runs in its own process. In addition to the standard maximum of eight content processes, there are also a few specialized processes such as one for Firefox extensions and another for calling up local files.įor more than three years now, Mozilla has been working on the logical further development of this concept, a page isolation, under the internal project name Fission. This architecture, developed under the internal project name Electrolysis, or e10s for short, separates the browser from its content processes, which brings improved security through sandboxing, performance and stability, since a website crash no longer includes the entire browser crashes.
Side insulation “Fission” brings more securityįirefox has been running with a so-called multiprocess architecture for several years. The selected theme is of course retained beyond that. There the so-called color schemes have their own temporary section, which will be removed again with Firefox 96. Firefox notifies you of this after the update, but the themes can also be installed later via the add-ons management.
