use to be my goto forr YEARS, but it got boughy out by a few different mobs. & ended up just wanting good money. Shame , I did like it, & was even paying the minimum, just for Joe's pocket money. It's now just a money grab.
There are several others now, just as capablem without the price.

Perfect for old dudes

I can't get on with this app at all. I've only got one site added so far, and it shows my user name on clicking the app icon - how secure is that? Can't wait to get rid of it.

Stupid and Useless, this DOES NOT import all of your existing Firefox passwords, so, really what good is this??? What am I missing here??? You have to start collecting our passwords all over from scratch when you start to use this program! Why bother?

After the update, Russian localization disappeared, the interface became incomprehensible

I can't find any instructions on how to use this extension. When i tried using my "master" password (so long, since it has to be at least 12 clicks long), I couldn't sign in to one of my sites. I had to use my old, site-specific password.

This shouldn't be recommended by Mozilla. This is a non-libre add-on to store and sync online passwords.
And the owning company is based in the USA. They will (or have) received request for user passwords like Lavabit did for their encrypted email.

Libre/Open source software should be essential to recommend an add-on. They are using Mozilla's work without reciprocating.

And it violates Principle 4 and Principle 7 of Mozilla's manifesto https://www.mozilla.org/en-US/about/manifesto/

Great app, saves time and frustration.
