Created attachment 488658 [details] Tarball containing the OpenSUSE patches. OpenSUSE includes patches for Firefox that make it integrate better with KDE Plasma 5 - notably, using the KDE file dialog instead of the default GTK+-based one, possibly among other things. Barring figuring out the dependencies, it would seem relatively easy to integrate these patches into the Firefox ebuild(s), ideally through a "kde" USE flag or some such. The attached tarball contains the (hopefully all) necessary patches - however if that's not sufficient, here's the link to the package on the OpenSUSE Build Service. (And just for extra reference, the Arch Linux AUR package.) https://build.opensuse.org/package/show/mozilla:Factory/MozillaFirefox https://aur.archlinux.org/packages/firefox-kde-opensuse/
I've been using those patches myself together with kmozillahelper (which is a requirement) in my local overlay, but they are huge and likely won't be added by Mozilla team as long as they are not upstream. The topic was discussed before...

The topic was > discussed before... I am not interested in this at all. ALL of the QT framework has been removed from upstream as there is not enough of a user base or developer base to support it.
