[tde-users] Firefox strange behavior

Hi all, having been testing Trinity for while & for the most of the time liking it! One annoying issue however is Firefox not working as expected – only in TDE, and not in/with other DEs/WMs, even KDE5/Plasma. For example, I can't save any web pages – neither via <Ctrl>+<S> nor right-clicking on "Save page as". It's the same with vanilla Firefox as well as with its fork Firedragon. Further though the latter doesn't prompt for not being the default web browser, Firefox does this always on start-up (because of Konqueror, I guess). And in both cases this can't be changed. What to do about it?
