I once had firefox x86_64 installed (because it was the default). But that one has problems with plugins (flash, java), which are much easily solved by using the i386 version. So I unstalled firefox, and installed it again using:

yum install firefox.i386

This worked, and even the plugins worked fine afterwards.

I did have some problems when uninstalling, because yum insisted on a whole load of dependencies going up to uninstalling the package 'firstboot' (wow!). However I can't remember the exact details anymore. I do not remember having to force anything; just reinstall a little bit more than I was expecting to. I do remember that after the erase/install, no particular problems were left and I used firefox since then without any problems.

Today came the update for firefox 3.0.2.

So I did "yum update". The depencies included xulrunner and devhelp.

However, yum complained about a conflict between xulrunner 1.9.0.1 being incompatible. So I erased xulrunner first (yum erase xulrunner).

And then installed firefox again:

yum install firefox.i386

it pulls in xulrunner as well, but two different versions for two different architectures (???):

============================================================================= Package Arch Version Repository Size ============================================================================= Installing: firefox i386 3.0.2-3.el5.centos updates 11 M Installing for dependencies: xulrunner x86_64 1.9.0.2-5.el5 updates 10 M xulrunner i386 1.9.0.1-1.el5_2 updates 10 M

and afterwards firefox complains:

$ firefox Could not find compatible GRE between version 1.9.0.2 and 1.9.0.2.

Any idea how to fix the fox?
