Works great !

It's worked seamlessly for years but it occasionally (like now) has a problem where I simply have to wait a couple of weeks or more for the "fix" to roll out.

LastPass has had multiple serious security breaches. I will never use LastPass again, nor will I use any other product produced by LastPass or GoTo.

I am locked out, can't remember my master password, and it's telling me I can't run the Account Recovery routine. The application is therefore useless for me.

Since changing owners this plugin is getting 'buggy'. They're changing the graphic UX but the functionality of the plugin in Firefox is not consistent anymore and small annoying bugs are slipping into the extension. Anything from small things like the cursor not being on focus in the password field when you have to fill in your password to bigger things like empty pages with just the Laspass logo appearing when you're supposed to log in. Also: sometimes the site is recognized because it's shown under the last-pass icon, but it refuses to automatically fill in the password.
