Is this a duplicate of bug 592577?

I can confirm Fx 4.0b11pre (Minefield) to have been showing this behavior for quite some time -- though I really, *really* prefer to keep it opaque (for Fx, not the whole OS).

Attachment: Changing the active tab makes the whole window transparent/opaque; the tabs have nothing special on them.

Added a screen-shot to better describe what I mean. If I change the active tab the whole window (may) change from transparent to opaque or the other way round.

Each tab will make the window either transparent or opaque, and will do so every time it's made active. Right now, my tabs make the window transparent but 3: add-ons, Office Outlook Web Access, and another one in localhost.

Closing this, as it appears to no longer be an issue. If you find that it is still an issue in Firefox 7, please reopen.
