I updated to Firefox/Mozilla 5 and can't open it - deleted download and reloaded but still nothing

I was running the former version of Firefox/Mozilla and was notified to update to the newer version of 5 which I did and have not been able to open it at all. I have enough hard drive and memory to run it on Windows XP operating system. Tried to go back to the older version but can't do that either. Right now I am using Opera but would much rather use Firefox as I liked it a lot. I am upgrading to another computer soon running the Windows 7 Professional - do you have any reports of Firefox 5 being unable to run on Windows operating systems?

There are a lot of Firefox 5 users still running Windows XP, but everyone's memory and drive space and graphics are a little different, so it's hard to make a blanket statement.

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 re-run the Firefox 5 installer to see whether that corrects the problem.

If the installer won't run until you exit Firefox, the program may be hung in memory. You can use the Windows Task Manager (Ctrl+Shift+Esc) to shut it down. Check both the Applications tab and the Processes tab.

Does that help?
