New release policy is madness--from one FF session to next, don't know what will work and what will not. Hello???

I have four computers at home between me, wife and kids and two at work--all using FF. I shouldn't need to work this hard to keep the browsers working right. Addons that worked for 5.0 aren't working for 5.0 now--many are not working with 6.0. I can't keep up. I'll have to give up soon and switch everything to Chrome maybe. I don't want to but I don't know what else to do--this new release policy is madness. I'm seeing similar concerns all over the place as I'm scrambling to resolve issues. I have spent my entire Sunday screwing around with FF!!! Is anyone listening???
