Full screen mode on linux hides the titlebar. This makes it impossible to move the window. If you happen to have a window in the upper right hand corner that is kept "on top" by your windowmanager, that means that there is no way to exit full screen mode (since it does not place mozilla "on top" and therefore all the little buttons in the top right are inaccessible).

What is full screen mode on Linux...
It was intended to be Windows-only for this release. I haven't seen this yet, but it sounds like it may be serious enough to disable the feature on Linux.
May I ask how i trigger fullscreen mode on Linux? I'd be interested in testing it. I thought it was disabled on Linux, and the feature futured? A simple solution would of course be the one requested over and over - a "restore" item in page context menu while in fullscreen mode.
This must be WM-dependent. On KDE 2.2 kwin, I can still see and reach the WM decorated titlebar just fine and resize the window.
Yes, this _would_ be WM-dependant... different WMs do different things when asked to resize a window to a particular size and when asked to put it in a particular spot (some count title bar some do not). Some also report the size of the titlebar when asked and some do not. I'm using AfterStep 1.8.0.
>'a _real_ security' Could you define the type of real security risk here?
Sure. The risk is that the offending page effectively turns off Mozilla's UI, makes Mozilla take up the full screen, and makes Mozilla uncloseable.... There is also a bug that I can't find at the moment about resizeTo() having similar effects that describes some other issues in detail.
Isn't the whole point of "fullscreen mode" that the window decorations such as title bars, menus, status bars, etc. are hidden? If you can see the titlebar, it isn't fullscreen mode. It sounds like what the user wanted was to "maximize" his window, not put the browser in "fullscreen mode". I'd call that user error, not a bug.
Please read comment 4 again. The _user_ did not put the browser in fullscreen mode. The user has no way to do that. The _web_page_ put the browser full screen mode. If the full-screen mode were not accessible to untrusted content by default this whole issue would be moot.
There was another bug about this...the answer I got was that this is very WM-dependent and hard to fix. The best fix would still be to make sure all WM's keep the titlebar on the screen. Some of them treat the (0,0) point of a window to be the top left corner of the content area, *below* the titlebar, which is what causes this particular problem. However, if we can't fix that, I agree that we should disable this function from content.
I think this is invalid by the new fullscreen mode. F11 will get you out, and there are, or should be, seperate bugs if we're misbehaving with GNOME or KDE panels.
> F11 will get you out Only if that keybinding is not used by your windowmanager, which it often is.
this seems to be ok now. full screen mode has its own (non-WM) buttons for minimize, restore and close.
Please read comment 0, sentences 2 and 3 again. On a typical AfterStep or Windowmaker setup, not a single one of those three buttons is reachable.
Right. And it can't be reenabled till this bug is fixed.
It would become discussable.... Whether it should be reenabled is a separate issue. In no case can it be reenabled while this bug exists, however.
the reason the titlebar goes away is that all OS chrome is explicitly clobbered. Some WM ignore that and display some of the chrome anyway. If you want the titlebar to not get clobbered, there appear to be 2 options 1. the easy solution (change the behavior of "hidechrome"): http://lxr.mozilla.org/mozilla/source/widget/src/gtk/nsWindow.cpp#4186 change "0" to "GDK_DECOR_TITLE" (and other relevant things for other toolkits) I tested this out and it successfully restored the titlebar under blackbox. 2. the hard solution: http://lxr.mozilla.org/mozilla/source/dom/src/base/nsGlobalWindow.cpp#1927 after hiding chrome, restore the titlebar. this is "hard" because there doesn't seem to be any way to alter the chrome of an existing window (except via "hidechrome").
Once Full Screen is fully implemented on X11, shouldn't users be able to get out of it using F11?
The F-keys are commonly reserved by the window manager for various window manager functionality.
