Rated 4 out of 5 stars

Just started using thunderbird and I'm losing some time configuring it.

Most themes are outdated and the old rounded tabs are an eyesore compared to the new Firefox Quantum theme. However thunderbird 60 does not work with Google Calendar provider...

This addon allowed me to have square tabs again!
I won't give you five stars because I can't disable the Aeroglass transparencies in Windows 10. But great job with everything else.
