Rated 1 out of 5 stars

Doesn't work with TB 64.0b2.

Citing a recent comment on my blog:

"Okay, so here’s the deal: XPCOMUtils.generateQI seems broken in both Firefox and Thunderbird nightlies, probably even in the beta versions. See for example https://github.com/mozilla/tls-canary/issues/171
As the addon crashes on startup with exception “TypeError: XPCOMUtils.generateQI is not a function”, I’d say that’s true for 63b1, and therefore it won’t work.

If you’re not a developer, go back to a stable version, if you’re a dev – well, deal with it ;) Not trying any bugfixing around a fuckup in beta TB versions, sorry."

Not citing Green Day: "Wake me up when the Beta ends." If you're running a beta version, don't bitch around (anonymously!) and give one-star ratings when stuff breaks. There's other ways to notify me of impending doom.

BETA != STABLE.
