Every time I go to add on the 1Password add-on, it will not do so. It doesn't automatically load the password as Firefox did before I added the 1Password add-on. Now, to enter a password, it's at least a 2-step process when before I tried to add this to Firefox, it was a 0-step process.

UX sucks. Blocking competing sign-in popups feature works really (not) great: it doesn't block LastPass when you enable it, and it blocks Firefox built-in manager when it's disabled.

The browser extension that has had the biggest positive impact on my browsing experience.

Unobtrusive and effective in the desktop browser

Minus one star as there is no option to not lock one password. As someone with a single user desktop, this is more an annoyance coming from Bitwarden but enough to make me rethink.

The browser extension used to lock and unlock with the primary app, but that's apparently not working any longer. The extension seems to want to work, but it just doesn't fill in fields, so I almost always just ignore it. I wouldn't bother with this extension, it really doesn't work well.

Brilliant. Works fine for the whole family. Easy-to-use private vault and shared vaults now save plenty of cross-questioning and getting niggled for kid's passwords by adding a kids vault. Works fine across apps on Windoze, Mac, iOS. Enough possibilities to add extra tags, notes, etc.
High-end IT-security guy in the team and he approves.
Kicked out LastPass, KeyPass and cryptic random notes. Don't miss them at all.

I love 1Password but the browser extension in Firefox is so unreliable it's infuriating. It Randomly appears and disappears, and I've found no help from trying to follow suggestions for fixing. PLEASE FIX THIS PROBLEM, 1PASSWORD!
