Firefox will not open after new update; Error: Platform version ‘1.9.2.13’ is not compatible

After accepting the new update I got this error message when trying to restart Firefox:

XULRunner

Error: Platform version ‘1.9.2.13’ is not compatible with minVersion >= 1.9.2.14 maxVersion <= 1.9.2.14

I have tried: - Opening in Safe Mode; same error - Uninstalling, deleting remaining info in C>ProgramFiles>MozillaFirefox folder, and reinstalling. - Updating Avast antivirus in case that was interfering.

Now when I try to start Firefox I get this message;

Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.

But there is nothing happening in the Windows Task Manager. Please, somebody save me from Windows Internet Explorer!!

Hmm, the first article suggests a clean reinstall, which I've already tried. The second regards a problem with the platform.ini file, but the contents of mine look normal (to me!); [Build] BuildID=20110218125750 Milestone=1.9.2.14 SourceStamp=a73120a6aa93 SourceRepository=http://hg.mozilla.org/releases/mozilla-1.9.2

I went to the Check your Plugins page and it said I needed to update QuickTime. While doing that I get the message; The feature you are trying to use is on a network resource that is unavailable. Click OK to try again, or enter an alternate path to a folder containing the installation package ‘QuickTime.msi’ in the box below.

when I click OK it says; The path ‘C:/Documents and Settings/User/Local Settings/Application Data/Apple/Apple Software Update/QuickTime.msi’ cannot be found. Verify that you have access to this location and try again, or try to find the installation package ‘QuickTime.msi’ in a folder from which you can install the product QuickTime.

I've run a search and can't find QuickTime.msi I also can't uninstall QuickTime using Add or Remove programs - I get this message; The installation source for this product is not available. Verify that the source exists and that you can access it.

I resolved the Firefox problem using the Profile Manager and making a new profile

https://support.mozilla.com/en-US/kb/Managing%20profiles?s=Managing+profiles&as=s

After this I was able to open firefox using the new profile. It seems I have problems with my Default Profile. Probably messed it up myself trying to do a 'clean' install incorrectly.

Hi! I received the same error as you, guys :

XULRunner

Error: Platform version ‘1.9.2.13’ is not compatible with minVersion >= 1.9.2.14 maxVersion <= 1.9.2.14

I resolved it very easy:

In the mozilla firefox folder go to platform.ini file, open the file and where is written "Milestone=1.9.2.13" change 13 with 14.

That's it!

I know of some cases where this has worked but if you check my log file in the second reply it already says .14 so that wasn't the problem in this case.

Might help some other people though so thanks.

Did you try that after reinstaling?

I experienced this error updating from Firefox 3.6.13 to 3.6.14 and resolved it by doing a 'clean' install' as described. It occurred again in updating from 3.6.14 to 3.6.15 and this time a clean install failed to rectify it. (Anyway, I don't want to have to go through this every time.)

Work-around: Shut down Firefox. Edit application.ini (typically "C:\Program Files\Mozilla Firefox\application.ini")


[Gecko] MinVersion=1.9.2.15


Change to 1.9.2.13 Save. Start Firefox. Dirty? Yes. Works? Yes. (Gecko is the forerunner or XULrunner)

Yes, it was after reinstalling that I checked platform.ini file and it looked ok. Think I probably messed up the default profile when trying to do a clean install. So maybe if I'd tried your solution first it would have worked...? Bummer because I lost all my profile info and had to start again. Glad I use the StumbleUpon Add-on; it saved all the sites I'd previously 'liked'.
