I have NEVER had the problems others experienced in Firefox, Chrome, or iPhone (but then I update regularly so that may be their problem).
I used a couple of other password managers and this is hands-down the best! Very easy to migrate, a great mobile app, and lots of great little extras included. A little confusing between the two different extensions (let's call this 4 1/2 stars) but stick to their Password Manager & Digital Vault and you'll be happy. Super tech support via real-time chat (no crappy/useless bots!)
Try NordVPN too!
