This used to be so awesome, but wow, lately it has become a buggy mess. I can never trust it to actually save an updated password, half the time I think it did, only to discover it didn't, or it would generate a new password for a site, but then silently generate another one and save that one in the vault instead, leaving you wondering why the new password you made for a website isn't working. And whatever they did to the interface made it so much worse from a user perspective.
But the final straw for me is random web-client-content-script errors I started getting whenever I would click certain buttons on websites. Took me hours to track it down to this extension.

As others have stated, the extension frequently breaks in a way that makes it think that you have no passwords saved. Fixing requires uninstall/reinstall. It happens about once a week to me.

Constant glitches. Can't reach server, etc. I can't even understand how a company like this can survive with such a terrible extension.

The Firefox extension won't load.

Stop wasting time  getting locked out of accounts or filling  passwords and  forms online! Instead, start wasting your time disabling and re-enabling, uninstalling and reinstalling, and otherwise constantly attending to this extension which seems to work perfectly - 60% of the time. I find it obnoxious when people complain about a product they're getting for free. Yet, I find myself here, writing a one star review for a product with a very generous free tier. But what am I supposed to do when this thing has wasted so much of my time and probably cost a couple years of my life by boiling my blood so many times.
