If the 1Password 3 extension is missing in Firefox 40 or later | 1Password Support
Starting in Firefox 40, Mozilla removed something called the “widget module” from Firefox. The 1Password 3 extension is old enough that it relied on the widget module, so it doesn’t work in Firefox 40 or later.

Does the classic browser extension still work for the latest version of Firefox? — 1Password Community
December 12, 2022 - As far as I'm aware you can still run version 4.7.5.90 with the latest version of Firefox. However, both 1Password 6 and the classic extension haven't been updated for many years and you might run into issues using these older versions of 1Password alongside the latest versions of Firefox and macOS.

r/1Password on Reddit: 1Password extensions disabled this evening [All Firefox extensions unavailable]
June 13, 2018 -

Hi r/1Password!

Update: Hotfix available

https://discussions.agilebits.com/discussion/comment/504110/#Comment_504110

There's currently an issue in Firefox which is causing all extensions, including 1Password, to be disabled. This means no extensions will work in Firefox until Mozilla resolves this issue. In the meantime, you can still use the 1Password extension in several other browsers. Here's the link to download the 1Password extension for Chrome and Opera:

https://1password.com/downloads/#browsers

Alternatively, if you have a 1Password account, you can use 1Password X (our newest browser extension) in any Chromium-based browser, like Opera, Vivaldi, and Brave:

https://support.1password.com/getting-started-1password-x

If you'd like to track the issue with Mozilla, you can do so here:

https://bugzilla.mozilla.org/show_bug.cgi?id=1548973

Once things have been sorted out on their end, please follow the steps outlined here to make sure the extension is enabled and up to date in Firefox:

https://support.1password.com/update-extension/#firefox

Please let us know if you have any questions about this. Thanks for your understanding.
