Hi all, (I've cross-posted to -x11@ since it appears this problem is related to X.org, not Firefox.)

FWIW I've tested with libkse, this doesn't change anything. However a friend of mine (Xavier Lapie <bana@docisland.org>) investigated the problem further and found the solution: Actually we are both using the X.org's radeon driver with: Option "AccelMethod" "EXA" According to radeon(4x) manpage, "EXA" is supposed to be faster than the traditional mode "XAA" but it is also newer and possibly unstable. Removing this option or switching back to the VESA driver solves the slowness. Sorry for the noise, I will send a mail to X.org's developpers.
