Not-so-happy LastPass user here: I evaluated alternatives, but LastPass is the only one which somehow works on Linux/Firefox. I have even tried to make pressure to 1password about that, without much success: https://discussions.agilebits.com/discussion/comment/410603/...
I stopped using browser based password managers and switched to KeePass. It's a bit more work to pull passwords and back them up, but for me it beats trusting cloud services with security critical data.
This! I love my setup. I use KeePassXC and sync my password db with NextCloud. I love having an open source password manager that is useful across all of my devices, be it Android, Linux, Mac or Windows.
+1 for enpass, using it to manage and sync passwords between android/iphone/ipad/mac/linux (via dropbox). The single wart is it doesnt autofill firefox on android, you have to switch to a custom secure keyboard where you can manually fill on a field-by-field basis once you've authenticated with master pass or fingerprint.
Another thing I appreciate is that there is an npm module to decrypt your own wallet; this gives me confidence that I can access my secrets if there is some problem with the app or company.
1Password does in fact work on Linux and Firefox -- although it's not prominently advertised for some reason; I usually have to search for the page.
We have a team of developers using macOS and Linux, and we use the team functionality to manage both personal and company passwords. We made the switch to 1Password specifically because of Linux support [1].
I couldn't make it work 6 months ago, they answered to the issue I referenced above that it wasn't officially supported and they never sent any updates about that on that issue, so I supposed that the situation stayed the same. I wonder why they don't update their issues anyway
I haven't used it myself, but it was created by Wladimir Palant (creator of AdBlock Plus extension), I believe after they examined the LastPass extension and were rather unimpressed with its security practices.
