Thunderbird version 3.0 is built on Gecko 1.9.1 and JavaScript 1.8.1, 
which powers Firefox 3.5 (except when it was 3.1) and Seamonkey 2.0
Firefox 4 (ex-3.7) uses Gecko 2.0 (ex-1.9.3) and JS 1.8.5 [no 
corresponding TB release]
Firefox/Thunderbird 1.5 is JS 1.6, Gecko 1.8.0, while Gecko 1.8 is JS 
1.7 and Firefox/Thunderbird 2.0.

I, for one, like sanity in versioning. As a developer, it means I can 
read "new in XXX 23" and know instantly where it applies, instead of 
having to track down a convoluted correlation chart.

Keeping the same version internally solves edge cases for issues like 
aurora/beta build versions, and I would in no way countenance a proposal 
to give the UI a different version number from the internal guts. For 
end users, the version numbers they care about are "up-to-date" and "not 
up-to-date." Let's not make it more complicated.
