Can you attach a screenshot?

• use a compressed image type like PNG or JPG to save the screenshot

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

• switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
• do NOT click the "Refresh Firefox" button on the Safe Mode start window

Hi cor-el

I dont know what I have just done, but the problem has solved it self. So now only the pages show when I hover or click on the firefox icon in the taskbar. Before when I did that it would show all of the windows and tabs at the same time, insted of just the windows and all of the tabs contained in the specific window in wich it was opened up in.

thanks
