Installing new version warning - tell me how many of enabled add-ons not supported, disabled support?



I recently upgraded to lastest version of Firefox (18.0) but i now find several add-ons are not supported by this version. I had waited but still several are not supported.

is there an add-on or an easy method that shows me when I get the Firefox alert "update available do you want to install?" (my preference setting is ASK) that firefox / or a firefox add-on scans my list of add-ons and tells me

1) 5/60 enabled addons are not supported on this current version

2) 2/10 disabled addons are supported on this version

3) or a way to tag add-ons to say, if these are supported in current version, then install it. if not wait.

I would like this feature, so then i can make a more informed choice to install the firefox update or hold.

I do have the add-on > cleanest add-on manager (but that does not help with this issue) > add-on update checker (but that does not help with this issue, it notifies when update of the addon available, and allows you to control when the add-ons are updated)

This Add-on will display Firefox version compatibility in the Add-on Manager window/tab - https://addons.mozilla.org/en-US/firefox/addon/is-it-compatible/

You may need to uninstall Cleanest Addon Manager for the above Add-on to work properly.

What version did you update Firefox from as a update from say 17.0.x should not be a issue except for say Themes and certain extensions like those supplied by antivirus clients.

Also it is not up to the Firefox browser to be compatible with the Extensions and Themes but the other way. Though as of Firefox 10.0 the majority of extensions should still work fine.
