I want to check my addon compatabilities BEFORE I try to upgrade to Firefox 4 (without checking each and every one manually) How can I do this?

Many people have posted frantic questions about problems downgrading from FF4 to FF3.6, because of incompatabilities with their Addons. I use a LOT of addons. I don't want to check each and every one of them manually for compatability. (And then repeat that in a few weeks, to see what's changed....) And I don't want to try upgrading to FF4 on spec, and then discover I need to downgrade because one or more of the addons I rely on doesn't work.

How can I check the addon compatabilities WITHOUT actually upgrading?

You can try the Is It Compatible? add-on which adds compatibility information to the add-ons manager - https://addons.mozilla.org/en-US/firefox/addon/is-it-compatible/
