The new version 93 of Mozilla’s Firefox comes with some juicy features including tab unloading, insecure download blocks and forced referrer trimming.
While the current version is still only available on Windows with MacOS and Linux to follow, the new tab unloading feature allows Firefox to unload tabs to prevent the browser from crashing when it is in low-memory situations on Windows. The feature unloads tabs, starting with the most recently used tab. However, tabs exist in the foreground or those that are pinned are not unloaded.
