Hi Raghav,

Are you actively working on this bug?  If you are not, then as a matter
of etiquette, I think it would be best not to change its severity.

Can you provide specific example URLs that do not work?

Did you try installing the gst-plugins-* packages?  I observed similar
behavior in the past.  I believe I resolved it by installing the right
gst-plugins-* packages, which is probably one of these:

gst-plugins-base
gst-plugins-good
gst-plugins-bad
gst-plugins-ugly

You might also have to adjust some settings in about:config.  I can't
remember if I did that or not.  Video in IceCat generally works, but
depending on the video you might need to jump through some extra hoops
to make it happen.
