Thunderbird after any upgrade always get another icon, separate from the pinned one in DF.

And sometimes taskbar buttons just get messed, pinned icons loose their order and regular window buttons get swapped.

I tryed to reorder by grabbin icons in taskbar, settin the right place, but it didn't solve.
Then I tryed to reorder in config window, but as before, I did't work.

If you need some tests, send me instructions on how I can get the right information for you.

Thanks for this fantastic software!
