Firefox keeps opening a new window every once in a while when I click on a tab to open it. It is happening quite a few times a day now and is annoying.

Chosen solution

Firefox 3.5 versions and later have a feature called tear-off tabs.
You can detach a tab from the current window and open it in a new window by dragging a tab in the browser window.
You can drag that tab back to the tab bar in the original window to undo that detaching.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

cor-el, thank you for the information regarding "tear-off tabs". I must have been moving to fast and this was what was happening.
