That can happen if the updater wasn't able to update (replace) all the files in the Firefox program folder (C:\Program Files\Mozilla Firefox\).
Download a fresh Firefox copy and save the file to the desktop.

This problem occurred shortly after updating to Firefox 5.0 I kept getting reminders to update to 5.0 When I finally decided to update, the first 4 or 5 attempts failed for one reason or another always with a different error message At some point after and extended shutdown of the computer 5.0 was initiated.
The updater wasn't able to update all the files and some were left as older versions.

Firefox worked and then when I shut down and restarted I suddenly started getting this message. What can I do?
Such an error is always caused by inconsistent files in the Firefox program folder (application.ini and/or platform.ini and possibly others) and your only option is to reinstall that version of Firefox, either via the software repositories or the Mozilla server.<br />
Be sure to delete all files in that folder before copying the files from that tar.bz2 archive.<

If you use ZoneAlarm Extreme Security then disable Virtualization and reinstall Firefox.<br />
Other security software may have similar features to prevent Firefox from updating files properly.

I noticed that firefox updated last night before I shut down my computer, then when I turned it on this morning I received the error message I described above. It will not let me open firefox.
I solved the problem by reinstalling the updated version and it now works fine. Thank you for getting back to me so quickly.

I cannot open Mozilla Firefox. Instead, a XULRunner dialog box appears with the message: Error: Platform version "6.0.2" is not compatible with minVersion >=6.0.1 maxVersion<=6.0.1 edit
Can you please tell me how to solve this problem? I have been running Mozilla Firefox on my Dell laptop with Windows 7 os.

I should have added, this popup relates to XULRunner. I suppose this is a support file that needs to run for firefox to open and run properly.

What is this about and how can I retsore access to Firefox on my pc?If you use ZoneAlarm Extreme Security then try to disable Virtualization.
