Thanks for writing it!   Would a back-port to firefox v2 of this (or
another solution) be feasible?

Indeed, though there may be a downside, particularly on remote X servers --
in that the x image doesn't get cached on the thin client's X server so
there may be considerably more network traffic.

I completely agree.  However, it's not clear to me whether the firefox
developers will be interested in implementing this approach.  One downside
is that evidently the video card is probably quicker at doing the resize
(or resample rather) than the CPU.

However, it would be great to be able to set a firefox setting for low RAM
X servers which did resizing entirely in the x client.   Do you think there
is much likelihood of this being implemented?
