Hello, I have had the problem for over a month that there is a thin white line on the outside of my Firefox website. I've tried everything to reinstall Firefox Delete Chace but it doesn't work.

Check that you do not run Firefox in Windows 7 or Windows 8 compatibility mode.

You can open the Properties of the Firefox desktop shortcut via the right-click context menu and check the "Compatibility" tab. Make sure that all items are deselected in the "Compatibility" tab of the Properties window.
