Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9pre) Gecko/2008041005 Minefield/3.0pre When you switch to full screen mode, no menu is shown when using Alt+letter shortcuts. Pressing e.g. Alt+F opens a hidden file menu and you are not able to leave full screen mode with F11. Instead you have to press Escape to close this hidden menu. If we want to support showing these menus, they should be visible. Otherwise they shouldn't be opened in hidden state.

still see this with Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1b3) Gecko/20090305 Firefox/3.1b3 Henrik, is this a regression? If so, perhaps bug 240859? BTW, lots of fullscreen mode bugs

No idea if this is a regression. Haven't checked this yet. Would be nice if someone could find the time to check with older releases.

I tested FF2.0.0.9 and behavior is the same. So not related to bug 240859, ... and I did not find an older bug to dupe to! cc: Michael from bug 240859

In the picture, we can see in the lower side a region that is unused by firefox, after that the windows task bar is show, the rigth side is not show fine, and finally, the in upper side is not the firefox title bar. This ocurr when there two or more firefox windows is opened, this not ocurr with the first firefox windows, ocurr with the other firefox windows.

Comment on attachment 371396 [details] screenshot for the wrong bug (bug 486962) Sorry, this picture is for bug 486962. But have any connection with this bug.

Still an issue in FF 4.0. (Mozilla/5.0 (X11; Linux x86_64; rv:2.0) Gecko/20100101 Firefox/4.0) Especially troubling is the fact that F11 does not work if you happen to activate a hidden menu. My suggestion is that Firefox should exit full-view mode when a menu is activated.

Still there. Also note that hitting F10 (Linux/Windows) in fullscreen mode activates the invisible menubar as well, so that you can't even leave fullscreen mode via F11 until you hit F10 again or happen to hit a menu command! That's nasty.

+1 Firefox 20 on Linux

In very old builds 2003-08-08-17-trunk.MozillaFirebird-i686-linux-gtk2+xft — 2006-12-07-04-trunk.firefox-3.0a1.en-US.linux-i686 * menus which have first been opened in normal mode work in full screen mode * menus which have first been opened in full screen mode first are broken also in normal mode Since 2006-12-08-04-trunk.firefox-3.0a1.en-US.linux-i686, menus never work in full screen, and don't break in normal mode. The bug is still present in 2013-11-13-03-02-05-mozilla-central-firefox-28.0a1.en-US.linux-x86_64.

I'm running Firefox 27.0.1 on Windows 7 with the US-International keyboard. In full-screen mode, the Menu Bar is "permanently" hidden rather than auto-hidden, and it is completely nonfunctional. There is no way to display or access it in full-screen mode, whether by moving the pointer to the top of the screen, pressing F10, pressing and releasing the leftAlt key, or pressing a leftAlt keyboard shortcut (e.g., leftAlt+v for the View menu or leftAlt+T for the Tools menu). (The rightAlt key is used for typing special characters in the US-International keyboard.) The only way to regain access to the Menu Bar (and its menus) is to exit full-screen mode. This is a MAJOR inconvenience for me, for two reasons: (1) I am using Tab Mix Plus's multi-row Tab Bar option, which eats up vertical webpage space in regular display mode. Full-screen display mode is very useful in recovering that space. (NOTE: changing the Tab Bar to a single row display in Tab Mix Plus does not eliminate the permanently hidden Menu Bar problem.) (2) I have placed most of my toolbar buttons on the Menu Bar. (I gather that that particular customization may be limited or eliminated in Australis, but I'm planning on restoring it with extensions). I use my toolbar buttons extremely frequently, and having to toggle back and forth between full-screen and regular display modes is not a practical option. For me, this qualifies as a MAJOR bug.

Related/duplicate of https://bugzilla.mozilla.org/show_bug.cgi?id=648504

So, in fact this bug has been fixed by the fix for https://bugzilla.mozilla.org/show_bug.cgi?id=1192655 -- pressing Alt plus a letter when in fullscreen mode no longer opens hidden menus, and thus pressing F11 to get out of fullscreen mode will always work. The desire of the other bug report (https://bugzilla.mozilla.org/show_bug.cgi?id=648504) is that Alt+letter should open the requested menu *visibly*, so that the menus can be used even when the menu bar itself is hidden.

I'd suggest this should be closed as a duplicate of bug 1192655. However, there is another bug blocked on this one and I don't really know what the status of that is, so I'm not closing this myself.
