Drop down menu disappears when you try to scroll down
After latest firefox update problems started. Some sites including my own have a problem with the navigation bar. Drop down menu disappears when you scroll down. Same sites work properly on other browsers.

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