Just an FYI but the Mozilla devs are at it again. When Firefox 3.2 comes out there will be a number of changes to how themes work. They've recently split the Mozilla 1.9.1/Firefox 3.1 branch from the programming trunk and I'm seeing some changes already in how the master theme is coded. There were 9 pages of changes to themes for Firefox 3.1 so we'll need to double check the Mac4Lin Firefox themes as we get closer to 3.1 coming out to see what breaks in our themes. Sine it's Firefox themes I have no doubt we'll probably have to tweak some things to resolve bugs they added for us. If you're testing Firefox 3.1 please let us know how the themes are working in comparison to Firefox 3.0.4 so we start getting an idea what we may need to do.
And you thought GNOME devs were bad about changing themes with updates.
