I use password manager browser extensions... but honestly they make me a little uncomfortable, and I'm slowly migrating away from them.

If your computer were a city, the web browser would be the high crime area. I may have my valuables in a locked safe, but it's a little bit self-defeating to carry that safe with me in the places where I'm most likely to be mugged.

If you have a malicious extension, then under XUL I think it is game over. WebEx probably offers more isolation and/or protection. Also note that a malicious addon can possibly also record passwords that are pasted in manually from a password manager, or auto-typed.

On the other hand a website should not be able to get at any password stored in (or pasted into) the browser except its own.

Exactly the same for me, Bitwarden works great, even on mobile.

Probably just a conflict w/ other extensions or something but, for me, LastPass's "beta" WebExtension quit working after upgrading from FF57 (developer edition) to FF58 (developer edition) on Arch Linux. It worked fine until then, though. It just throws an error saying my list of sites/passwords/whatever can't be downloaded and to try again. Likewise, the newer "non-beta" extension does the same thing.

Edit: Spent 30 seconds to troubleshoot. If I disable uBlock Origin and then login to LastPass (extension), it works fine. So just a small conflict somewhere. YMMV.

Same boat here, happy with the switch to BitWarden. I'm happy to have a mobile app that isn't subscription based and developers that are willing to go after the new (unlike lastpass' disinterest).

this is exactly what happened to me also. now, i have fully migrated to bitwarden on all my browsers.
