Rated 5 out of 5 stars

I've used this addon for a long time and it's always worked great -- it's a vital part of my daily workflow. Needless to say, I was upset to discover it was automatically disabled by Thunderbird today with the message: "ToneQuilla is incompatible with Thunderbird 15.0.1."

Is there a way to make it work again? Quickly? :)

UPDATE: OK - I installed the addon "Disable Add-on Compatibility Checks" and it appears to be working fine now. I'll update this review if anything else goes wrong.

This review is for a previous version of the add-on (1.1.0). 

This has been reported before. It is some glitch in the AMO update process. A version that is unchanged, but claims compatibility internally through Thunderbird 24.*, is at
