WARNING : as announced previously, the firefox-3.5-0.21.beta99 package install this new version replacing the version 3.0. So, it also removes the old firefox3.

Start by reading :

As always :

yum --enablerepo=remi update firefox

No xulrunner update, this RPM provides his bundled Gecko engine.

Actually the some extensions are not compatibles and will be disabled.

I start to test the new features and I expect yours feedbacks.
