FF 48.0.1 Windows XP SP3, Lenovo T41 Pentium M 1.6Ghz, Radeon 7500

Youtube videos (360res) plays choppy (unusable to watch) in firefox, 100% CPU.

Same URL played in VLC smooth (50% avg CPU)

FF: youtube plaback, Nerd Info - video/webm vp8.0 vorbis, 640x360.

VLC: codec info; google/on2's VP8 video (vp80), 640x360, 30fps.

what I tried: - forced FF to use H264 codec, (adobe gmp) , same results, choppy.

- turned FF setting (use hw acceleration on/off).

- FF safe mode.

- full screen FF/VLC (vlc no problem full screen).

- tried latest adobe flash.

- installed lubuntu on this laptop and FF 48 (VLC under ubuntu plays comfortably smooth and cpu at 80%).


Is there any way I can play smooth youtube videos in FF ?

or the google/on2's VP8 codec is superior to vorbis codec ?

There may be an issue with your graphics card driver software. If Firefox cannot use your GPU to accelerate video decoding, all of the load falls on the CPU. Does anything in this article help: Upgrade your graphics drivers to use hardware acceleration and WebGL.
