User-Agent:       Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:6.0a1) Gecko/20110422 Firefox/6.0a1
Build Identifier: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:6.0a1) Gecko/20110422 Firefox/6.0a1

Command-W (close tab) doesn't work much of the time in the last few nightly builds.  On most tabs, it works fine.  On some tabs, nothing happens, although you may see a brief flash of blue on the file menu.

Reproducible: Sometimes

Steps to Reproduce:
1.  Open a bunch of tabs to different sites.  I've had this happen on YouTube, but also on many other sites.
2.  Try to close the current one with command-W
3.  Sometimes it closes it.  Sometimes, nothing happens.
4.  Sometimes, switching to something else, like another tab, then switching back, allows it to close.

Actual Results:  
Sometimes it closes it.  Sometimes, nothing happens.

Expected Results:  
Tab closes with command-W.

Works for me on Build identifier: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6;
rv:6.0a1) Gecko/20110425 Firefox/6.0a1

Also, could you see if the issue occurs if using Firefox in safe mode:

How about with a new, empty testing profile? (Don't install any addons into it)

Reporter, have you something new to add to this issue?

As of the 4/30 build, I still get the problem.  I restarted in safe mode and did not get the problem.  However, I then restarted in normal mode, with everything enabled, and did not get the problem.  The problem seems intermittent.  I definitely get it sometimes, but not every time.

This seems to be happening mainly (or entirely) on pages with flash on them.  Still getting the problem on the 5/13 build.

Can this be bug 78414 ? Can you narrow it down to flash plugin catching the focus and keypresses?

Just got it again, on another flash site.  I tried clicking outside the flash part of the window, and was able to command-w, but could not before doing so.  It does look like flash is stealing focus from the (newly rendered) window.  I didn't click on flash.  Even if I had, it shouldn't override basic window controls.

Thank you, that is exactly what bug 78414 is about - determining and implementing which main keyboard shortcuts shouldn't be sent to the plugin but always to the browser. I think bug 78414 will fix your problem.
