Browser Development • Re: Linux Pale Moon with Qt toolkit

I mean, depends on the definition of "possible."

Like, if you mean could it be done in theory? Yes, not only has Basilisk-Dev been tinkering in private, but Mozilla did once support Qt a long time ago, they just removed it and standardized on GTK. So yeah... it could use Qt if we really wanted it to. Do we have an implementation ready? Well, not really. It isn't a feature we've seen a lot of call for.

I think for the foreseeable future, we are likely tied to GTK3. Supporting that is going to be our lifeline that gets us through the deprecation of GTK2 on mainstream Linux, and it is still at the core of some major Linux desktops like MATE and Cinnamon. If our goal really were supporting modern GNOME, I'd be considering trying to do GTK4... but I feel like until/unless MATE, XFCE, and Cinnamon go GTK4, that transition would be premature since currently GNOME is the only major desktop using GTK4.

As for Qt? I feel like that isn't really worth considering unless we find the majority of our Linux users are on KDE Plasma or something instead of a GNOME fork, and I'm suspecting we have more people on Cinnamon, XFCE, MATE, and even GNOME itself than anything else, though I haven't taken polls.
