Perfect? No.
Best I've found? YES

Name a password manager, and I've probably used it for personal use or as an IT Systems and Solutions Engineer. Proton Pass has been the best one by a wide margin.

Any difficulties I've faced while using the Proton Pass extension can usually be traced back to the target website or app and how it's built/configured, and not to a problem with Proton Pass itself.

There is still room for improvement, particularly around security key integration, but I've encountered far fewer headaches with Proton Pass and its Firefox extension than with any other password manager.

Also, if past updates are any indication, I definitely remain hopeful that it will continue to get better.

This has been the best password manager I have ever used. It would be great if the browser extension would allow us to zoom in on the info or enlarge the font because sometimes it is too small to read.

Mostly really happy with the add-on, but the following issues/features take it down from five stars:
- disable autosave for this website doesn't seem to work
- defaults to individual vaults rather than all log-ins, which means I often have to manually change to find the password that I need (and was very confusing before I realised this was happening)
- can't/doesn't offer auto-populate when pages have a small pop-up login rather than the login elements being displayed in the page (although this depends on the exact website)

Awesome, fast and easy to use
