OK Fine, it’s really Swiftfox, but the problem is really inherent to Firefox.
My Swiftfox 3.0 kills my KDE4 Desktop Effects. Which pisses me off because I love my shinny objects.
Everytime I accidentally drag select some text and then accidentally attempt to move the selected text, everything hangs up and poof. There goes effects.
I solved this by disabling the drag-drop feature in firefox but I’m still not happy.
To disable drag drop, go to the location bar and type about:config
look for “nglayout.enable_drag_images” and disable that (set it to false).
