When I go to a drop down menu, for example bookmarks, I mouse over the text and it turns color with a dark bar; can this be fixed?

I am running Firefox 5 currently. Ever since the last update to Firefox 4 and currently with firefox 5 I have had this issue. The dropdown menu is normal when it first drops down. When i move my cursor over the text in the menu it changes to a dark blue bar and remains that way until I close the dropdown, it resets until i dropdown and mouseover again. When I make a selection in the menu it works fine.

I have also noticed that the buttons in the browser and in certain websites have a "sweetspot" you have to hit for the button to function. In past versions if you clicked anywhere on the graphical button it would function.

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


In Firefox 4 Safe mode disables extensions and disables hardware acceleration.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

If disabling hardware acceleration works then check if there is an update available for your graphics display driver.
