741445 - Firefox maximizes itself when switching virtual desktops

Status: RESOLVED WORKSFORME

(Firefox :: Untriaged, defect)

Description

[Mark Reid [:mreid]]

In Firefox nightly from April 2nd, running on Ubuntu 11.10, Firefox maximizes itself when switching between virtual desktops.

Steps to reproduce: 
- Open firefox in a non-maximized state
- Switch to another virtual desktop (I use ctrl+alt+right-arrow)
- Switch back to initial virtual desktop (ctrl+alt+left-arrow)
- Firefox is now maximized.

Is this still happening? Does it happen with a new profile or in Safe Mode?

I've been using Nightly on Ubuntu since before April (albeit currently 12.04) and have not seen this issue.

What window manager are you using?

OK, it *was* still happening (16.0a1 (2012-06-27) on Ubuntu 12.04 now), so I tried starting in Safe Mode and it stopped.  Restarted again and started up normally, and now it's not happening anymore.

Strange.

Oh well, if it starts happening again, I'll reopen.

I can confirm that this is happening again.  It seems to have started around the time that I upgraded Firefox to version 20.0, and in the same way described in the initial email.

I am running Ubuntu 12.04 LTS with metacity window manager.  The problem persists even with Firefox in safe mode.

Additional info:

The problem does NOT occur when using compiz window manager.

The problem does NOT occur when using Ubuntu's guest account with either compiz or metacity.

It's not happening here running Nightly 23.0a1 (2013-04-19) on Ubuntu 12.10.  Feel free to reopen this bug if it persists.

Further info, which may require a renaming of the bug:

- The problem only occurs if the auto_maximize_windows field is TRUE in metacity's configuration.  If it is set to FALSE, the problem vanishes.

- The problem is not restricted to Firefox.  It occurs for any window whose size is nearly the entire screen.  (Typically, only the web browser window is so large, which is why it only seemed to happen in Firefox.)


So the new steps to reproduce the bug are:

- Be sure that the metacity (not compiz) window manager is running.

- Verify that auto_maximize_windows is true in the metacity configuration.  Either:
    a) run "gconf-editor" and make sure that the "auto_maximize_windows" field in apps -> metacity -> general is checked
  or
    b) run "gconftool-2 --type boolean --set /apps/metacity/general/auto_maximize_windows true"

- Open any window in a non-maximized state, but make its window very large - taking up nearly the whole screen.

- Switch to another virtual desktop (I use ctrl+alt+right-arrow).

- Switch back to initial virtual desktop (ctrl+alt+left-arrow).

- Large window is now maximized.

OK, so it sounds like this is a bug in metacity.  Would you like to file a bug over in the Gnome bug tracker? https://bugzilla.gnome.org
