Today I try palemoon for the 1st time. After installing version 24.6.2-1 on an Arch Linux i686 system (from palemoon-bin package in AUR), my impression is totally amazing and satisfying. Really love this browser.
However, html5 videos using codec h.264 do not play at all. I've set the option
media.gstreamer.enabled to true. Package
gstreamer0.10-ugly-plugins used for h.264 and mp3 decoding is already installed.
I use these sites to test:
https://www.youtube.com/html5 and
http://www.quirksmode.org/html5/tests/video.html
Could someone help me plz?

This must have worked without any problem, so I guess perhaps it's because of the browser or the package itself. Should I compile the source package?
