The Firefox bars and Apple menus unhide together, and then the Apple menu suddenly retracts as I move down to the Firefox toolbars, causing it to shift up just as I click. I always end up missing the bookmark I was aiming for, or accidentally clicking on a bookmark while aiming for the back button, or similar. Driving me crazy. Is there any way to keep the Firefox menu bars from shifting upward until the mouse hoovers away from all the bars?
