Help! After this morning's update installed, an error message appeared that read: "XUL Runner. Platform version '6.0.2 is not compatible with miniVersion =6.0.1 maxVersion =6.0.1" Now Firefox won't open or respond at all. What's the fix?
Error dialogue box appeared:
XUL Runner. Platform version '6.0.2 is not compatible with miniVersion>=6.0.1
maxVersion<=6.0.1
This happened a few minutes ago when I clicked on the Mozilla icon.
If you use ZoneAlarm Extreme Security then try to disable Virtualization and do a clean reinstall.

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.
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.
* Firefox 5.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Uninstall your current Firefox version.
* Do not remove personal data when you uninstall the current version.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder] and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox. -
When I try to start up Firefox, I immediately get a samll window with the above message. It looks like this:
XULRunner
Platform version 8.0.1 is not compatible with miniVersion>=7.0.1
maxVersion<=7.0.1Be sure to delete the Firefox program folder before (re)installing Firefox as the usual cause of this problem in that not all files got updated properly and some .ini files like application.ini and platform.ini are still older versions.

I cannot open Thunderbird. Above message appears on screen.
I suggest you download a fresh copy from getthunderbird.com and reinstall. I do not know what has caused it, but a reinstall should refresh the files and fix it.

I also did a System Restore and that didn't clear the problem, either.

I tried some of the instructions for opening in Safe Mode but to no avail.
my first suggestion would be to reinstall. No uninstall, just run the installer again to replace any corrupted files (it sound like something may well be corrupted.)

Windows XP SP3. Worked this morning! Now I get this error
XULRunner keeps saying "error: platform version 20.0.1 is not compatible with >min version=19.0 <max version=19.0" how do i fix this?This is caused by a broken (corrupted) Firefox installation where not all files have been updated properly.
Do a clean reinstall and delete the Firefox program folder before reinstalling a fresh copy of Firefox.
Download a fresh Firefox copy and save the file to the desktop.
*Firefox 20.0.x: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
*Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will also lose your personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

If you keep having problems then also create a new profile.
