Trouble in Firefox: Wrong Logins, Blank Extension, etc.
Unfortunately, in the latest versions of Firefox, there seems to be some changes that are causing issues for the 1Password extension. We've been looking into this trouble with Firefox but have not been able to find the cause. We started to see this issue within Firefox 23, and unfortunately current versions of Firefox do not seem to have resolved it. It seems that it is related to opening new windows. It doesn't happen every time, but if you open enough new windows, you will eventually get a JavaScript exception, and the 1Password extension will cease to function properly.
For now, there four possible workarounds:
Switch to 1Password 4 for Mac. This is the preferred option as we are integrating with Firefox in a different way in version 4 which is not affected by the Firefox changes.
You also have the option to join the 1Password for Mac beta instead of or in addition to the release version of 1Password 4 for Mac.
Switch to Safari or Chrome until Firefox resolves this issue. This may not be ideal depending on your workflow.
- Downgrade to Firefox 22 and disable automatic updates. This is not ideal from a security perspective.
- Never use more than one Firefox window. This may be the most tricky to implement since it's very easy to accidentally open a new window or browse to a site which does it automatically.
