After Firefox just upgraded, I noticed it did a check to on the compatibility of the Add-Ons I have. Should any be incompatible, then the add-on gets disabled. The rationale being, “Add-Ons which do not work under the current version should not be enabled.”

Seems like I as the user of the software really ought to have a choice:

1. (Current) Immediately upgrade the browser and disable any incompatible add-ons.
2. Check add-on compatibility first and delay the browser upgrade until add-ons are all compatible.
3. Check add-on compatibility first and prompt the user to choose when to upgrade. (Whether #1 or #2 is desirable.)
4. Allow the user to choose which add-ons are too important to be disabled and delay the browser upgrade until an add-on version is available which is compatible. Then offer to upgrade both.

Maybe not enough people care Mozilla takes away their functionality?
