Previously I was successfully running Firefox 13.0.5 ( 32-bit version) on the 64-bit Red Hat Enterprise Linux v6.2.

I need to use a 32-bit Firefox because I need to use a 32-bit eclipse.exe and various other 32-bit tools on this 64-bit environment.

Today the RHEL v6.2 got upgraded to v6.3.

Now firefox 13.0.5 (32-bit) will not start, it gives this message: Error: Platform version '10.0.5' is not compatible with minVersion >= 13.0 maxVersion <= 13.0


Note: the RHEL 6.3 has a 64-bit Firefox 10.0.5 (but I am explicitly starting the 32-bit Firefox 13.0.5 via /opt/firefox13/firefox. --- How do I get the32-bit Firefox 13.0.5 running again ?

Chosen solution

SOLVED For some reason the Firefox 13.0.1 directory (for me this was /opt/firefox13) had its libxul*.so as a symbolic link to /usr/lib/libxul*.so. I unlinked the symbolic link, and ensured that the libxul*.so was the one that came with Firefox13. This solved the problem, Firefox 13.0.1 now runs correctly again.

Typo in my previous post, I mean firefox 13.0.1 (32-bit) and not 13.0.5. Symptom remains unchanged, starting firefox 13.0.1 gives: Error: Platform version '10.0.5' is not compatible with minVersion >= 13.0 maxVersion <= 13.0

Hi, I'm having the same problem with version 14.0.1, could you possibly explain how to fix this in a step by step process? I'm having trouble finding 'libxul' and I have no idea what I am suppose to do when I do find it. I'm running Waterfox on Windows 7, 64 bit.

You usually get such an error if not all the files were updated properly and the content of application.ini doesn't match the version of the libxul.so file in the Firefox installation directory.
Such issues are usually caused because files were used by other applications during an update.

It should work if you download a full version and delete all the files in the Firefox installation directory and copy the files in the tar.bz2 archive to that folder. If it is a problem with a version that has been installed via the repositories then it may be more difficult to fix it, but uninstalling and reinstalling should work in this case as well.

You can find the latest Firefox release in all languages and for all Operating Systems here:

Uninstalling and re-installing seemed to work. I still had some issues pinning it to my taskbar but after trying a few times it seemed to work. Thanks.
