When multiple tabs are open with one to chrome://browser/content/browser.xul, closing that tab with ctrl-w freezes the tab bar and viewing window.

Reproducible: Always

Steps to Reproduce:
1.Open a new tab
2.go to chrome://browser/content/browser.xul in the new tab
3.close the new tab using ctrl-w
Actual Results:  
Tab bar freezes and viewing screen turns grey.

Expected Results:  
Tab closes like any other tab.

found in 1.5 and 1.6a1
I found an old report where these steps led to a browser crash, apparently that was fixed but not well.

Not really a freeze, just press ctrl-t and everything goes back to normal.

It's still funny though ;)

It does not crash as such but it messes with the tab bar, you can't open or close any tabs untill you go crtl+t.

Cheers.

opening the browser chrome inside of the browser chrome might break, but there's no practical reason to do so, and content can't make it happen, so this is a bit silly.

I can't reproduce this in 3.0a6 or current trunk. Opening browser.xul does seem to interfere with focus a bit (can't use ctrl-w to close the tab immediately after opening it - reminds me of the way that flash captures keyboard controls) but after it's closed the active tab is visible and the tab controls work correctly.

Considering comment 3 and that everything works after closing the tab I think this is now WFM.
