Out of curiosity, what UI toolkit does Thunderbird use? GTK or the UI system derived from Firefox?

- AnonHP 6y agoIt used to be XUL, but since that was deprecated and Firefox doesn’t support it, for a while Thunderbird was still using it with a plan to switch out. The larger plan for Thunderbird is to use “web technologies” (meaning HTML, CSS and JS). IIRC, this move is already in progress.
- jabl 6y agoTB has much less manpower than Firefox, so they're mostly following whatever Firefox does. Firefox is indeed in the process of getting rid of XUL in favour of web technologies, but AFAIK it's not done yet. And yes, on UNIX platforms the "XUL backend" is gtk.
