CSS class .mozilla-only does not work with Thunderbird

[tdulcet]

This line does not work in Thunderbird:

AutomaticSettings/EnvironmentalOptions.js

Line 38 in f62226d

return browserInfo.vendor === "Mozilla";

since the vendor name is blank:

I tested it with both Thunderbird 78.9 ESR and 88 Beta. We should either submit a bug to them on BMO or change that line to use the name instead.

This is currently blocking Thunderbird support for Unicodify, although context menu support is also blocked by bug 1656506.

Oh nooo… uhm…

We should definitively submit a bug, given it clearly is a bug…

However, if you'd need it, I'd be fine with a workaround like this:

// Thunderbird is explicitly checked as a workaround as Thunderbird does not return the vendor correctly <bug link>
return browserInfo.vendor === "Mozilla" || browserInfo.name === "Thunderbird";

OK, I just created bug 1702722. Note that the getBrowserInfo() function is currently only available in Firefox/Thunderbird, so both the isMozilla() and isFirefox() functions will fail in Chrome.

OK, that should work for Unicodify in the meantime...
