You can use Firefox or LastPass, they are mutually exclusive and wont work together. Firefox will become unuseable

The LastPass add-on for Firefox has been god awful for as long as I can remember using it on there. Recently it has been losing the connection to LastPass forcing me to log in to LastPass over and over again. This has made my Firefox browser unusable.

There's a bug in this extension that results in minimal connectivity on firefox as well as taking up lots of compute power! I checked on htop and this was resulting in my RAM getting guzzled up as well. Also LastPass for some reason doesn't sync seamlessly across devices so I've lost some passwords. The web interface doesn't adapt well to mobile either. Overall this could be built better
