There are a few websites where it cannot detect the login/register boxes, but there's probably more blame on those websites than the extension itself. Other than that, it works great. You can do basically everything available in the desktop/mobile apps and it has a nice synchronization with them.

The best extension any password manager have ever created. Proton pass is simply the best choice!

One of the prettiest and easiest to use open-source password managers out there.

Faster than Bitwarden, overall as good or better.

One Proton extension works exceptionally! Importing passwords from Firefox, etc. works great. Love it!

This password manager is the best, most user-friendly, and effective one I have come across. Runs smoothly on all my devices.

I've used many password manager - so far this one is the best

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.
