Uses 100% CPU, blocks other extensions from running.

The 1Password extension work very well for a year, but about 4 days ago it wouldn't open. I deleted the extension, restarted and reloaded the extension. It worked for 2 days and then again it wouldn't open.

Funktioniert leider nicht mehr richtig unter Firefox (andere Browser funktionieren ohne Probleme) . Nach Neuinstallation funktioniert der Passwortmanager wieder, leider nur bis zum nächsten Neustart von Firefox. :-(

Was working great, then a few days ago it quit working in Firefox.

This app is terrible. The support sucks and trying to get anyone to address my billing issues has been impossible. I signed up and could never get it to work. I signed up with a different email and somehow they linked the two and now they have locked the first one that we could never make work and so that locked the second one too, which we paid for. Now we are locked out. TERRIBLE SUPPORT. Don't use it way to complicated to make work and support.

Adding to similar feedback from other users. Since a recent update, this extension no longer works in Firefox. I have tried removing and reinstalling the extension, etc. Nothing happens when you click on the extension, and no autofill of passwords on websites either. It is useless now (whereas it was almost perfect before) As this feature is an essential element of the membership we are paying for, this clearly needs to be fixed.

1Password Firefox extension was updated July 15, 2025. The 1Password Firefox extension now no longer works. Clicking on the 1Password icon in the Firefox toolbar does NOTHING.

Has stopped working since the latest update

I cannot add a 1Password account to the extension if it has MFA enabled on it. When trying, the extension setup simply sends me to the 1 Password Web UI and does not store the account in the extension.

Been trying to recover my wife's account for almost 6 months. Nothing you tell me to do recovers this account. I have tried and so has she but there is a problem with with the directions. The items you say are suppose to pop up don't. The BOT is useless as is the help you try to provide by clicking on help. Can't speak to a human and when getting the code for them to email you. It takes days for them to help. Very unhappy with 1 Password.
