This version is not compatible with 1Password. How do I go back to the previous version that worked for me?

I was able to use 1Password before this latest update 4.0.1 and now it's useless. How do I revert back to the browser that worked for me and 1Password. I had over 100 passwords linked to the prior version and I need this remedied quickly. What can I do other than use another browser?

Hi, 1Password is compatible with Firefox 4.0.1. Are you using 1Password 3.5.9?

It sounds like Firefox is caching some data from a previous version. You can fix this by completely uninstalling the Firefox extension and reinstalling it:

1. Make sure Firefox is not running.

2. Launch 1Password from your /Applications folder

3. Click 1Password > Preferences > Browsers

4. Uncheck the box next to all versions of Firefox

5. Launch Firefox and click Tools > Add-ons > Extensions. Make sure that 1Password is *not* listed.

6. Step #5 is the most important step so I'll repeat it again here :) Launch Firefox and make sure 1Password is not there.

7. If 1Password is appearing in the Extensions window, click the Uninstall button on the 1Password extension and quit Firefox.

8. Return to your 1Password window and check the box next to Firefox. There are two versions: 3 and 4. Pick the one that you have installed.

9. Restart Firefox and click Tools > Add-ons > Extensions. Make sure that 1Password is listed.

After following these steps, the Firefox extension will have forgotten everything about previous versions and should work correctly.
