I received the following error when attempting to use HP SimplePass Identity Protection to manage my passwords; Firefox doesn't know how to open this address, because the protocol (dpql) isn't associated with any program. How can I correct this?

I use HP SimplePass Identity Protection to control my passwords. Everything was fine until I updated to Firefox 4. Can I remove version 4 or is there a solution to my problem.

You'll have to downgrade to the previous secure version I regret to say. See https://support.mozilla.com/en-US/questions/799388


Go to Download Firefox v3.6.17 and download it to the desktop.

Then go to Add/Remove Programs, scroll down to "Mozilla Firefox" and remove it, choosing to keep your bookmarks, customizations etc., (don't checkmark the box).

Then reboot and delete the folder called "Mozilla Firefox" at this location: C:\Program Files\Mozilla Firefox

Finally run the installation file you downloaded to the desktop earlier.

Your bookmarks, customizations etc., are maintained in a different location and will become available to you again once you complete the installation.


After you complete the installation, go to the Plugins Check page and update those where necessary.
