Once in a while it doesn't work properly with firefox.

отличное приложение!

Many times, it cannot save new vault. From both auto-recognized popup and moz-extension page. Chrome extension works great but FireFox one does not.

It "works", but it slows your computer everytime there is a form. If you are a developer that has to test a lot of users and passwords for a single form, it can be slow as hell.

The score would improve a lot if they would allow you to define sites where it should not be enable for. Like how the adblocks addon works.
