User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:16.0) Gecko/20100101 Firefox/16.0
Build ID: 20121005155445
Steps to reproduce:
After upgrade to FF 16.0, I have multiple tabs open and I right click a tab and select "Close other tabs" the option in General for "Warn me when closing multiple tabs" is unchecked.
I am prompted with the "Confirm Close" dialog box, Regardless of how the "Warn me when closing multiple tabs" setting is set. The setting appears to have no effect.
The tabs should close with a dialog prompt if the setting is unchecked and should prompt me if the setting is checked.
