Why is that every time I open Firefox I do not have all my SPEED DIAL sites that I created? Also, Firefox will not open when I click on it to open; it just flashes the page like it is trying to open, I have to disconnect from the network provider and then Firefox opens. What is going on with this new Firefox? I want to downgrade to the previous version; no problems with that version.

Regarding your Speed Dial list, I'm guessing that was created using an add-on. Can you check to see whether it was disabled because it wasn't compatible with Firefox 4:

Tools > Add-ons > Extensions

If there's no update and you can't live without it, sure, you can reinstall 3.6.16. 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 downgrade myself!
