It’s been a while since I used it, but Librewolf had a habit of showing the bitwarden extension’s window at the wrong size.

I was able to fix this by disabling a “resist fingerprinting” setting, but it’s annoying to have to do stuff like this in the first place. I really wanted to have an exceptions list that included certain websites for fingerprinting resistance, but I never found a clear way to do it.

There are a few other examples of settings that I had to tweak in order to make the experience as good as Firefox.
