So I have seen comments that bitwardens extension works and want to check if no script does. Since libre wolf is just configuration I figure most stuff should work but not real sure. I looked to see if there was something like a pinned questions thread which I would normally put a minor question like this. Considering recent news maybe instead a moving from firefox pinned thread for awhile first.
It’s built against the latest version and kept up to date with it, so you should be fine. The only extension I had an issue with was KeePassXC, but because it communicates with an application outside the browser. I had to symlink a single directory and now everything works just the same.
