If you don’t have enough to do with testing the public SUSE Linux 10.0 betas as they are I have some stuff for you as the next round of mozilla.org releases is near. I have new XulRunner and Thunderbird packages out there for 9.3 and 10.0. Both have enabled Pango font rendering and XulRunner has canvas support in addition.
New SeaMonkey packages will follow soon. If you now ask about Firefox: I have to merge forward the changes for the official 10.0 version to Firefox 1.5b first. The packages which are already available are not up to date.
