Somewhat of a PSA for Qt users:
On Linux, Firefox will now default to the XDG portal file picker if available, rather than the GTK3 one, which is usually better integrated with the user’s desktop environment, and more powerful. https://www.firefox.com/en-US/firefox/149.0/releasenotes/
Edit: I talk about a patched version below, but it was an about:config toggle in more recent times.
Always needed a patched version of Firefox before for that. Presumably most distros will transparently throw that patch out of their Firefox package, so likely don’t have to do anything.
But well, you don’t specifically need a patched version anymore for that, so if that’s a separate package on your distro, you could consider using the normal package again. Although, I believe there’s also still patches floating about for using the KDE mimetype system…


I’m a “developer edition” user (beta channel) running multiple profiles from multiple system users, and the only change I noticed weeks ago was the file picker not opening at all 😬
Fixed by running firefox with
dbus-launch. So that was +1 for dbus over systemd in the race to make less shit work expectedly, while killing unix/posix in the process.wow sucks if that’s true. why wouldn’t they just fallback to GTK+3 file picker when dbus isn’t working well?
i also kinda have dbus killed on my system, gotta see if i get this issue after my distro gets ESR 153…
I had to do some manual configuration to make the XDG portal filepicker work correctly in Niri, but after that I haven’t had any problems
There is a reason why Linux isn’t POSIX compliance, Unix and POSIX sucks.
UNIX and POSIX is awesome. Any operating system not following these standards suck, such as Windows and DOS.
What’s the reason?
Nah, dbus sucks. And it’s intended replacement, dbus brocker, even more, because it’s a wrapper around systemd calls, doesn’t work with any other service manager.
