Ublock Origin is an obvious one, but I also can’t stand not having Foxy Gestures anymore. It adds customizable mouse gestures, so you can set it up to have easy swipes to go back a page, reload a page, close a tab, etc, and it feels wonderful and smooth to use compared to just using the traditional buttons to do everything. Honestly it’s kinda wild to me that this isn’t more popular now that people are so used to phone gestures. It’s good for the same reasons!
Firefox Multi-Account Containers has to be one of my favorite extensions. Mixing work accounts and personal accounts in the same browser session but in different tabs has made my workflow much more efficient. You can force bind sites to a container so that you don’t accidentally use your personal account for anything workplace related.
This is has been so useful in my attempts to go FireFox full time. I always had Edge and Firefox on the work laptop to separate things when needed, but the containers completely eliminated that.
My one critique would be if the assigned links wouldn’t open an empty tab when that specific container opens.
Have you figured out a way to combine it with windows, such that each window has a designated container, and all tabs open in that container?
This one. I need to use Farcebook occasionally and this allows me to stay logged in without getting tracked elsewhere. Same for my Google account.
Definitely one of my favorites. My only wish is that they had a more flexible way to predefine lists of domains and containers and/or do wildcard matching for domains.
