I am using the latest firefox with tab mix plus and tabgoups manager. I have maybe 50 or 100 tabs oben in different tab groups. When I shutdown firefox and start it again all tabs and tab groups are perfectly rebuilt.

But I have also many pages open that are behind a standard http auth, and these pages all request their usernames and passwords. So during startup firefox pops up all these pages' http auth windows. And they block everything else in firefox, they are like modal windows. (I am involved in website development and the beta versions are behind apache http auth.)

I have to click many times the OK button in the popups, before I can do anything. All the usernames and passwords are already filled in. (And the firefox taskbar entry blinks and the firefox window heading also blinks, and focus switches back and foth, which also annoys me. And sometimes the popups do not react to my clicks, because firefox is maybe just switching focus somewhere else. This is the worst.)

I want a plugin or some way to skip those popups. There are some plugins I tried some time ago, but they did not do what I need, because they require a mouse click for each login, which is no improvement over the situation like it already is. This is not about password storage (because firefox already stores them). But of course, if some password storing plugin could heal this it would be great.
