1Password Firefox extension used to work fine, now does nothing

I am having the same issue on firefox on a pc.  I can't get logged in to some of my programs at all.

I have removed the plug in and re-added it, I have restarted my computer and it still isn't working.  Now trying to get you an error log report wand when I click inspect nothing happens. 

As title. When I open Firefox, all URLs just hang with what looks like an https issue. Disabling the 1Password extension, quitting Firefox, reopening Firefox, and re-enabling 1P fixes the problem until the next time I quit Firefox.

Incidentally, the Launch Chatbot button on https://1password.com/contact-support goes to https://support.1password.com/?openChat but does not open a chat.

1Password extension for Firefox 8.11.0.29

Firefox 140.0.4

macOS 10.15.7

(Why were the fields for this info removed?)

Over the last month or so my 1Password Firefox browser extension would stop responding. This was occasionally associated with a Firefox crash. This time I looked further into it and found via the Firefox Task Manager that it was using 100% of CPU. When I killed 1Password process and restarted the extension, the extension was working again.

I don't know if this is relevant but I keep a high number of tabs and windows open most of the time. Even when I shutdown my system. This allows me to have many tabs open all the time which I find useful.

Is there more I can do to determine the cause and fix it?

Extension version: 8.11.0.29
1Password version: 8.11.0
OS Windows 11, upgraded from Win 10 recently.

I am having the same problem (same version too). I also tried disabling extension and re-installing. Please fix bc I now need to use a different browser. 

I noticed that the 1password icon looks different than it used to (see attached). The black outer ring is missing (it is still there within Edge).

Same problem here. Firefox Developer Edition 141.0b9 (64-Bit) on macOS Ventura 13.7.6 on Intel Macbook. 1PW Extension 8.11.0.29 Stable

I have this problem too. It occurs on several different computers where we use 1Password. Initially, disabling and re-enabling the add-on helped, but then it stopped working. I tried deleting the add-on completely and reinstalling it, and it worked for a while, but then stopped again. The Windows application works fine, but there is a major problem in Firefox 140.0.4. It works in other browsers. 

But it seems to me that other add-ons are also freezing. For example, I have vidIQ Vision, and I can't click on it, and I tried to install NordPass so that I would have its icon next to it, but I can't click on it either.

Hello @cofiem, @DuchVeliky, @grimbuehler, @GaryH, @DoctorBrown, @Calion, and @egerlach! 👋

I'm sorry that you're running into issues with 1Password in Firefox. I haven't yet been able to reproduce the issue on my end and I'd like to gather some more information. Can you reply to this post with the following information so that I can try to reproduce your environment: 

1. What version of 1Password are you using?
2. What version of Firefox are you using? 
3. Are you using a Mac, Windows PC, or Linux device? 
4. In Firefox, while the issue is happening, open the task manager by navigating to about:processes, what do you see for CPU usage for Extensions? 
5. Are other extensions also unresponsive? Or just 1Password? 

I look forward to hearing from you.

Can anyone confirm if disabling Adblock plus makes any difference.

I have the same firefox+1pass extension+desktop 1pass on 3 different windows pcs. I disabled Adblock on one machine that was experiencing this issue and that seemed to fix it. My other pc seems to run fine while adblock is still enabled. Not the most conclusive solution but just wondering if anyone else has the same experience.

Just searched for others, found this post. Happening here also, about a week now.

firefox   142.0b2 (64-bit)
1password firefox extension Version 8.11.0.29    Last Updated July 18, 2025
1password desktop software on Win10 Pro Version 8.11.2

Desktop software works fine, never issues. Firefox extension every couple days, first thing in the morning it seems i go to click the extension icon pinned, and clicking just does nothing. My two other installed extensions is Adblock Plus and FoxClocks. No issues with either of them. 

Issue matches up pretty well with the Last Update to the extension.
