Firefox is now better at surviving these situations. And of course, there are the tab hoarders, (no judgement here). Or perhaps those users simply trying to play a memory-intensive game or using a website that goes a little crazy. We believe this may especially benefit people who are doing heavy browsing work with many tabs on resource-constrained machines. Unloading tabs allows Firefox to save memory leading to fewer crashes and avoids the associated interruption in using the browser. On Windows, out-of-memory (OOM) situations are responsible for a significant number of the browser and content process crashes reported by our users. The tab’s scroll position and form data are restored just like when the browser is restarted with the restore previous windows browser option.

This feature is currently enabled on Windows and will be deployed later for macOS and Linux as well. Loading that extension in Firefox give the error above.įor your reference here is my manifest.Starting with Firefox 93, Firefox will monitor available system memory and, should it ever become so critically low that a crash is imminent, Firefox will respond by unloading memory-heavy but not actively used tabs. Then pack that from the command line using 7z a -tzip test.xpi in that directory, which creates my zip file called test.xpi containing the two files. While troubleshooting, I made a minimal dummy extension which doesn't do anything, consisting only of a manifest.json and dummy.js file. The add-on downloaded from this site could not be installed because it appears to be corrupt. xpi, and then choose Install Add-on from file and select my. zip (not within a subdirectory or anything, the archive just directly contains the files) and rename it to.

Only in debug mode I can do Load Temporary Add-on, select the folder with my extension, and that works OK. Unlike Chrome, it seems Firefox can't install unpacked extensions or add-ons. Works fine in Chrome, but doesn't work in Firefox. I have my own browser extension with some personal website customizations.
