Comment 27 for bug 2036098

Whatever changes we made fixed the FileChooser, so that's great.

We probably need to fallback to kde since lxqt (even upstream) only implements that one interface. So that means we should probably do "default=lxqt;kde;" in our portal.conf.

Here's a weird quirk, though: I can't open files from within Firefox. Curiously, it complains about there being no OpenURI interface, but Kubuntu, which offers both the gtk and kde portals, neither of which implement that interface, works fine.

Seems to me that's a bigger problem than not being able to save the page.
