Some how, without asking my foxfire updated to 4.0 and I don't like it. How do I go back to my previous version?

more options

I have seen Firefox 4.0 on another computer and don't like what you have done to it so when it asked if I wanted 4.0 I always said NO. This time when I booted up and opened firefox it said updates were being installed and when it finished it was 4.0.

I want to go back to my previous version. How do I do that?

Check that your automatic updates setting has not changed. I recommend "Ask me what I want to do".

If you have the orange Firefox button, tap the Alt key to display the classic menu bar, then

Tools > Options > Advanced > Update mini-tab

What don't you like about Firefox 4? Maybe it's easy to change?

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 4.

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.

Note: I haven't actually tried this myself!
