Useful for end-users Rated 5 out of 5 stars

Thanks for creating this add-on. It is a great example of filling a gap in, IMO, essential missing housekeeping functionality.

Adding Thunderbird compatibility would be appreciated.

I have a very large profile. It simply isn't possible to prevent "stuff" from happening . Adequate maintenance instrumentation and tools are doable, Over reliance on "nuke and reinstall" common in the windows world is passing the buck. That bags the end user.Adding invalidateCachesOnRestart to the runtime api addresses the issue. Unfortunately. that's in gecko 2,0. FF4 may soon be ready for prime-time. I haven't checked yet, but think it take more time for a TB/gecko 2.0 release.
