I confirm this issue in Firefox 4b10.
First, I did some testing in Windows (Firefox 4b11pre on Win7) and the problem doesn’t exist there. Then I did some more testing on OSX and can confirm that the issue persists in the latest FF4 nightly. This is the current behavior in OSX: - When going in fullscreen mode, Firefox tries to add a "Full Screen" button to the FIRST toolbar. Not a specific toolbar (navigation or tabs bar), but simply the topmost bar. - The "Full Screen" button it adds uses the style for Navigation bar buttons, even if the toolbar it’s added to is the Tab bar. - If the button is already present in the topmost toolbar, it is not added. - If the button is already present in another toolbar, it is added to the topmost toolbar nonetheless. If I remember correctly, on Windows Firefox doesn’t try to add the "Full Screen" button. If the current basic behavior—making sure there is a "Full Screen" button available when in fullscreen mode—is wanted, the implementation must be fixed. Possible solutions (which may complement or contradict each other): - Search ALL toolbars for a "Full Screen" button. Don’t add one if there’s already one. - Always add button to the nav bar. If nav bar is disabled, either add to the topmost existing toolbar or don't add the "Full Screen" button at all. - If adding to the topmost toolbar, test the toolbar type and make sure to use the right button style.
