I have a bio-metric fingerprint scanner on my laptop that doesn't seem to be compatible with Firefox 4. When i swipe my finger to open an account the following message appears:

"Firefox doesn't know how to open this address, because the protocol (dpql) isn't associated with any program."

This didn't happen before I updated, and if it continues to happen I will swtich browsers.

It sounds as though one of your plugins or extensions did not update. Does anything helpful happen if you update from:

Tools > Add-ons > "Gear icon" button > Check for updates

If you have to roll back to 3.6:

First, make a backup of your computer for safekeeping. To back up Firefox, see Backing up your information.

Next, download and save Firefox 3.6 to your desktop for future installation. http://www.mozilla.com/firefox/all-older

Close Firefox 4, and uninstall it. Do not remove your personal data and settings, just the program.

Then finally you can reinstall Firefox 3.6. Unless you have installed an incompatible add-on, it should pick up where you left off. If there are serious issues, please post back with details.

Note: I haven't actually tried this myself!
