[15:21] <fvogt> wolfiR: Got it with -jsdebugger [15:21] <fvogt> It doesn't seem to be KDE specific. My guess is that part of https://github.com/mozilla/gecko-dev/commit/5b97708fef0e696b3fc6d5a10b350c495507b966#diff-fb7c6539255e9cbe1a9be9e10a41da55 is missing [15:22] <fvogt> "TypeError: fp.show is not a function" in jar:file:///usr/lib64/firefox/omni.ja!/components/nsHelperAppDlg.js:1091:13 [15:23] <fvogt> Indeed, https://www.rosenauer.org/hg/mozilla/file/tip/mozilla-kde.patch still uses fp.show [15:24] <fvogt> Needs to use fp.open(aResult => blabla) instead
