In bug 1282866, I have removed the QT code from the Firefox tree with the approval of the active peer. That code is not currently maintained by any team.

I have looked through the bugs in the Widget: Qt bugzilla component and I believe all of these are no longer relevant because the Qt code has been removed. If you believe that this bug is still valid, please move it to another more appropriate bugzilla component as you reopen it.
