So, everytime I open a new tab (about:newtab) or just a white screen (about:blank). It would be better, Firefox displays my desktop instead (or what's 'behind' firefox) to work more efficient.
I thought to try Firefox's Add-On 'Stylish' to solve this problem, but those scripts are only for Windows with Aero support.
So... any other ideas how I get a transparent page/screen in Firefox?
EDIT To clear things up: I don't want the whole window transparent!
