User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:61.0) Gecko/20100101 Firefox/61.0
Build ID: 20180326220108

Steps to reproduce:

I've removed a tab from a window creating a new window, and moved the tab back to the original window.


Actual results:

When I've moved the tab back there was a blue vertical line.
Moving the tab in the same window has made the vertical line disappear.


Expected results:

The blue vertical line should disappear.

I have tested this issue on latest Nightly build and latest Fx release build using Mac OS X 10.13.3 but could not manage to reproduce it. 

Can you please retest this using latest FF release and latest Nightly build (https://nightly.mozilla.org/) and report back the results ? When doing this, please use a new clean Firefox profile, maybe even safe mode, to eliminate custom settings as a possible cause (https://goo.gl/PNe90E).

I think the right component would be Firefox::Tabbed browser. Please change if this is not the correct component.

Doug, could you please check if you can reproduce this on Mac?

I can't seem to do anything to reproduce this. Tried moving between different DPI displays and resizing windows before moving the tab back. Let me know if you have any other ideas. Otherwise, resolving this as incomplete?

Classic WORKSFORME I'd say. :)
