tracking-firefox flags aren't for suggesting something is important. If you think it's important, work with the leads of that module to get it prioritized.

Comment on attachment 530616 [details] [diff] [review] patch v1 I hope you are willing to take the review for this, Ehsan :) The main fix here is to call UI.setActive() after all tabItems are shown again. So they're not arranged when hidden. The second test case covers bug 624692 that is fixed by this patch, too.
