Was I duped into downlaoding FireFox 5 Beta?
A pop up box came along and said to update to Firefox 5 beta, so I did now I can't get Firefox to work.

It is possible that you are still on the beta update channel if you ever installed a Firefox 4 beta version or a release candidate.
You can check that by looking at the pref app.update.channel on the about:config page.
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.
You can use the Filter bar at to top of the about:config page to locate a pref more easily.
If the value of that pref is beta then it is better to download and install the latest Firefox 4.0.x release.
