Thank you for pointing out that I needed to update some of my software -- I went ahead and did that. As for preferences, I tried everything those two sites offered and none of them solved the problem. I did find a user.js file that contained information on the mp3tubetoolbar. I went ahead and erased the information and saved the txt file but that didn't do the trick, so I deleted the whole user.js file. That also didn't work. I then deleted the prefs script file but when I restarted, the mp3tubetoolbar was still the default.

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). * Don't make any changes on the Safe mode start window. See: * [[Troubleshooting extensions and themes]] * [[Troubleshooting plugins]]

That didn't do anything...
