Thunderbird extension support

[eyalroz]

I suspect this is probably supported in Thunderbird extensions as well (both the regular extensions in the new WebExtension-like flavor). But - can you verify that this is indeed the case?

Hi @eyalroz! I'm not too sure what you're referring to - care to clarify?

[eyalroz]

You write that the code has been:

Tested in Chrome 82-83, Firefox 77-78, IE 11, Edge 82-83, Safari 12-13, Node.js 4-14, & PhantomJS 2.1.1.

can you test it in Thunderbird? Versions 52, 60, 68 and 78?

I noticed we don't currently have Thunderbird detection in Platform.js, and would be fine adding support for that. However, I'm not interested in adding the maintenance burden of testing in an email client. Since Firefox and Thunderbird both use Gecko, Thunderbird should be able to run Platform.js similar to Firefox.
