User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:33.0) Gecko/20100101 Firefox/33.0 Build ID: 20141013200324 Steps to reproduce: 1. Start Firefox and open a second tab. 2. With the second tab open a site that causes the dialog "Password Required" to appear. 3. Try to close the first tab. Actual results: The tab can't be closed. Expected results: Since tabs can also be changed while entering the master password I think it should also be possible to close them.

It's a modal dialog. I'm not sure how you're saying you can switch tabs while it's open, but I *am* sure that we shouldn't spend time on fixing one-off painpoints for this dialog instead of just converting it wholesale.

> I'm not sure how you're saying you can switch tabs while it's open I have rechecked this just to go sure: I'm indeed able to switch tabs while the "Password Required" dialog is open.
