This is my biggest complaint about Firefox, and I'm a) an add-on developer in my personal time and b) a Mozilla employee who spends 40+ hours a week working on addons.mozilla.org. I swear we're working on fixing it :) In the meantime, sorry it's been a hassle. I wish we hadn't switched to rapid release without fixing add-on compatibility. We honestly didn't realize how hard it would be to get right.
