Can I delete the preview option? When I roll over items if I don't move the cursor soon enough I get the "preview". I don't like it, need it or want it. Thanks

type in the address bar '''about:config''' then press the button '''i'l be careful i promise''' then type in the bar '''browser.allTabs.previews''' then double click on it to make it '''false''' Do the same with: '''browser.ctrlTab.previews''' exit firefox and restart. thank you Please mark "Solved" the answer that really solve the problem, to help others with a similar problem.
