overall experience: really good.
issues here and there but nothing major since I can't really remember to any at this moment

Great password manager. Found out that if a site makes changes and the URL is different the password manager won't recognize the site and not auto populate which is OK because I know it won't populate a phishing site. Its an annoyance that maybe you can look into but I'm thinking you can't fix.

Working as intended

Only thing stopping me giving it a 5/5 is a lack of ability to scan barcodes with the premium version

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!
