I don't know about you, but everytime they release a newer version, it breaks most of the extensions I have installed and then I have to either fix them or wait for new releases, this is getting tiring. If you are going to release an upgraded product at least have the curtosey to insure that it is downwardly compatable with prior extensions, and give a little lead time to the developers of the extensions so that they can have newer versions at the ready.

This will be the second time in 2 months that I will have to reconfigure Firefox to my liking, I would be willing to give up some of the customization that I am able to do if only for a stable upgrade path
