Description of problem: By default, yum update "up"grades all packages, including firefox, without any easy way to go back. Version-Release number of selected component (if applicable): 7.0.1 How reproducible: always Steps to Reproduce: 1. yum upgrade Actual results: It blindly performs controversial "upgrades" as well as non-controversial ones, resulting in broken add-ons. Expected results: It should warn about controversial upgrades (such as Firefox, KDE4, Gnome shell, or whatever other "usability nightmare du jour" ...), and give the user the possibility to opt out of those, and a possibility to go back if he missed one of those. Additional info:
I guess you want this feature for yum, not for Firefox itself, right?
I'm not sure which component (yum or firefox itself) would be responsible for this. I guess, at the very least, a 3.6.x version of firefox compatible with the current distribution release would need to be kept available in the repositories.
For Firefox we follow the Mozilla policy, we ship what mozilla offers to linux users by default because Fedora is supposed to be "bleeding-edge" distribution. If you need something more conservative try Red Hat Enterprise Linux for instance (or some free variant).
