youtube HD video in SeaMonkey

October 13, 2015 — BarryK
If you are running the latest Quirky 7.2.x, with SeaMonkey 2.35, there is a limitation with playing HTML5 videos at -- up to 360p only, and no full-screen.

720p and 1080p
To get these higher-density modes, you have to go to "about:config" (type into the URL-bar) and set these two to "true":


To enable playing full-screen, in about:config set this to "true":


Some discussion is here:

One very annoying thing about SeaMonkey, and I presume Firefox, is that it won't play h264, only webM videos. Even though Quirky has gst-libav (which is documented as what SM needs for h264).

Anyway, I will see if I can get those about:config settings preset as true for the next release of Quirky.


I haven't tried this yet, but this is an addon that implements true full-screen in SM:

...and explains why it is needed in SM 2.35.
