Middle click not opening link in new tab. Windows 7 Firefox 17.0.1
Middle click suddenly stopped opening new tabs when links are clicked on. I was running 16, but updated to 17 (latest) to try to fix the problem. I am using a Logitech mouse and keyboard. Worked until this week.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
Do not click the Reset button on the Safe mode start window or otherwise make changes.
