will updates for ff4 re enable my favorite add ons,which were automatically disabled due to incompatability with ff4?

I need my best add ons updated as soon as possible. I'm primarily asking about sxipper. I have to fill out forms constantly,however I am no longer able to do this because sxipper was disabled when I upgraded to ff4. I'm considering going back to the earlier version of ff.That way i can get sxipper back,right??also will add on updates re enable my add ons which were disabled? why does this always happen when ff comes out with a newer version? how can I get around it,it's very stressful.
