I made the fatal mistake of updating to Firefox 5.0, and I hate it. None of the tool bars I had work and are now gone, I don't like the layout of the homepage, I really want my 4.0 back, but every time I try to download version 4.o, it routes me to the 5.o download, and I don't want 5.0. Is there any way for me to reinstall the 4.0 version?

Due to security vulnerabilities, rolling back to Firefox 4.0.1 is not recommended. Firefox 3.6.18 would be the safer choice.

Here's the process to roll back:

First, I recommend backing up your Firefox settings in case something goes wrong. See Backing up your information. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)

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

Close Firefox 5.

You could install Firefox 3.6 over it (many have reported success) or you could uninstall Firefox first. If you uninstall, do not remove your personal data and settings, just the program.

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