MP3 support in Firefox stopped working for me a few versions ago (I don't remember which, exactly), and when it still did not work after upgrading to 35.0, I decided to investigate again. Eventually I thought that maybe MP3 support was not provided by any of the installed gstreamer plug-ins (I expected gst-plugins-libav to provide it), and installed gst-plugins-mad. And, well, MP3 playback started working again. So I wonder whether Firefox with USE=gstreamer should depend on gst-plugins-mad? Or at least print a post-installation message warning about lack of MP3 support? Reproducible: Always Steps to Reproduce: 1. emerge firefox with USE=gstreamer 2. try to play an MP3 at, e.g., soundcloud, or run the test suite at http://www.areweplayingyet.org/ Actual Results: Playback of MP3s fails. Expected Results: Playback of MP3s succeeds. % emerge --info firefox Portage 2.2.14 (python 3.3.5-final-0, default/linux/amd64/13.0/no-emul-linux-x86/desktop, gcc-4.8.3, glibc-2.19-r1, 3.17.8-gentoo

It already depends on media-plugins/gst-plugins-meta: [ebuild NS ] media-plugins/gst-plugins-meta-1.0-r2:1.0 [0.10-r9:0.10] USE="X a52 aac alsa flac jack lame ogg opus theora vorbis wavpack x264 -cdda -dts -dv -dvb -dvd -ffmpeg -http -libass -libvisual -mms -mp3 -mpeg -oss (-pulseaudio) -taglib -v4l -vcd -vpx" ABI_X86="32 (64) (-x32)" 0 KiB So if you set USE=mp3 globally or set it specifically for media-plugins/gst-plugins-meta, then you should already have had MP3 support. Oddly enough, www-client/firefox-35.0 decides to be different and cherry-picks some gst-plugins-* packages to depend on instead of the meta-package.

Sorry, I should have been more clear: I was, in fact, referring to the Firefox 35.0 ebuild. The dependencies were changed because of bug #515198, where one of the proposals actually had a dependency on gst-plugins-mad; the implication (in my head at least) being that said dependency change broke previously working MP3 support. And now that I look at that bug again, I notice that it is *not* closed. Oops. Should I comment there instead?
Multimedia group asked us to depend on specific packages rather than the -meta, since apparently the -meta is only meant for inclusion in @world by end-users, or something. The subset listed at this point is minimal, but I will add gst-plugins-mad to the list as well. I won't be revbumping ebuilds though so this change won't -really- take effect userbase-wide until firefox-38.2 or firefox-40.
Gst-plugins-libav as of version 1.4.5 advertizes its mp3 decoding now, so there is no need for a gst-plugins-mad package to be installed. Since 1.4.5 is current stable I bumped the dependency minvers for mozilla-38 and mozilla-39.
