I offer to do it and, on changing from tab with opened modal dialog to another do one of next things: 1. Hide the dialog. They will be showed only when user change tab back. 2. Do not hide, but always draw dialog only inside tab's rectangle, shaped by it's border. So no code for hiding them will be writed. Tab mechanism will hide it automatically when user changed the tab. Also any modal dialogs must not block interface of the browser outside the tab. Reproducible: Always Steps to Reproduce: 1. Open tab with the modal dialog. 2. Try to change to another tab or do something with the browser.

Dupe of bug 59314? Although there are so many open modal bugs it's hard to say.

I say yes
