[16:05] <MikeRL> Gnome-shell update today broke the ability to grab Firefox by the open areas of the tab bar with the title bar disabled. Grabbing via title bar is fine. Also, some extensions like DING (Desktop Icons Next Gen) broke.
[16:06] <MikeRL> I have to get to my job, so I don't have time to debug, but I'll leave this here since everything is logged. Might very well be a bug. 
[16:08] <MikeRL> I even disabled all my shell extensions. Still have grabbing issues.
