I'm not seeing thin lines in the screenshot you posted, so can you give more detail on where to look for them ?
Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.
- switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window
I just found out the lines on the screen! i am sorry! somehow the screenshot is not showing the lines!
