I have the bookmarks toolbar set to always show. They automatically arrange themselves from left to right. It would be good to be able to arrange them in other ways. Like right to left, in the center, or any other way. Ultimately, the entire browser is not OLED safe. Any icon or button or anything that stays in the same place will wear out the pixels being used to display it. In general, Firefox should be more OLED safe. However you think it can be. And I'd like my bookmarks toolbar to be displayed after I press f11 and then move my cursor to the top.
