Click the star in the urlbar twice, so it gets highlighted, and the bookmarking/tagging UI appears. 2. Try to use system hotkeys like Alt-Tab, Alt-space, or something you use to switch or move windows between workspaces. 3. Try using Firefox hotkeys like Alt-F or F1. Actual results: 2. Nothing happens. Ctrl-Shift-arrow selects text in the content area. 3. Firefox hotkeys work. Expected results: Things like Alt-Tab should never been overridden by normal applications. PS: Same happens in the Download Manager "(i)" UI.

Still there in both places in Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9a8pre) Gecko/2007083104 Minefield/3.0a8pre

Also in the Larry identity pop-up.

I'm pretty sure that this is because of http://bugzilla.gnome.org/show_bug.cgi?id=344059. Can't think of a workaround offhand though.

This is a keyboard grab for menus which is expected on Gnome; that part is not a bug. The other portion of this bug is a dupe of bug 393398, because this should not be a menu -- it's a dialog.

The bookmarks popup is neither a menu nor a dialog, so no this resolution isn't correct.

I don't think this blocks based on comment 3 and 4, minusing. If its felt that this is a mistake, please renom.

No progress on the Gnome bug, minusing for 3.1; Neil, is this basically invalid though, as it's a Gnome bug?

I don't believe this is a GNOME bug per se, as I see identical results on KDE. Alt-tab and PrtSc do work much as expected on Windows under these circumstances. Presumably Windows implements these system keys in a different way, as the application normally has little control over them unless hooking the keyboard at a low level. (Alternatively perhaps the cause is some special-case handling that doesn't work with Xorg's keymaps.) The address autocompletion in Epiphany and Evolution under GNOME is unaffected. IMO the most annoying example of the bug in current trunk is associated with the autocompletion popups for the URL and search bars in Firefox, and the address autocompletion in Thunderbird (bug 611461). I don't recall the bug in FF2. While the key-handling bug also affects several other widgets, such as the colour-picker widget and the Ctrl+D bookmark panel, these are deliberately invoked by the user; on the other hand, with autocompletion the user may need to very something with a fast task switch. The Alt-tab bug does not affect controls that inherit from nsIMenuBoxObject because the first press of the Alt key closes the popup. Popups that are derived from popup or general however need special code to get Alt-tab working, and PrtSc doesn't even work when a menulist or menu is open. The attached deals with the annoying case in autocomplete.xml, such that the first Alt-tab closes the dropdown, and subsequent ones invoke the task switcher. However, I wouldn't suggest for a moment that this is a fix to the general bug, which is probably somewhere deep in the fundamental popup implementation. I've also played unsuccessfully with ignorekeys, accessibility and capturing vs bubbling event handlers, so suggest the resolution is either to add special key handling to each control to close the popup, or to look at the popup implementation.

Not sure if this if a good idea, but it should be Linux-only at least. (Inside an #ifdef MOZ_WIDGET_GTK2)

Note that the patch in bug 545429 also fixes this.

Can someone verify that this is now fixed?
