Firefox gave me a warning about a site and I set an exception. The site that was warned against has asked me for a screenshot, but I can't find how to remove the exception in order to replicate the warning message. How do I remove the exception?

The site was JustCloud.com, and it wasn't every page that triggered the warning. I've looked through Options: Security, Advanced, etc., and can't find access to the stored exception in order to remove it. Below is the URL of one page that triggered it:

How did Firefox showed that warning?

Was the a pop-up on a sliding bar at the top of the browser page or a message on the web page?

Do you remember any content of that message?

Was it about a certificate (secure connection)?


Rename the file "permissions.sqlite" to permissions.sqlite.sav in the Firefox Profile Folder to remove all exceptions (cookies, images, pop-ups, software).

If renaming didn't help then you can undo and rename the file permissions.sqlite.sav to permissions.sqlite to get back the old exceptions.

You can use this button to go to the Firefox profile folder:

  • Help > Troubleshooting Information > Profile Directory: Open Containing Folder

Please update Firefox to the latest version via "Help > About Firefox" or "Help > Check for Updates" The Firefox Firefox/4.0.1 version that you currently run is no longer supported with security updates.
