.. in which AaronP states: "Thanks for reporting this. I took a look today, and it appears that Firefox is using an enormous pixmap that exceeds the GPU's maximum rendering dimensions, causing software fallbacks. While we will attempt to make it as fast as possible, performance would be greatly improved if Firefox would render using surfaces that fit within the maximum renderable dimensions."

The bad launchpad.net performance in Firefox is bloody annoying, no matter who is to blame. It does not help that launchpad.net itself is a very slow website with high load-times per page view. Makes for a sluggish impression in total..
