The firefox36-3.6-0.2.beta2 package install this new version besides the version 3.5. So you will have 2 entries in the Internet menu.

WARNING : a backup of your profile (.mozilla/firefox directory) seems mandatory.

Start by reading :

As always :

yum --enablerepo=remi install firefox36

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.

This version will be soon the only available in remi repository, remplacing the current 3.5
