@dietrich hi, from Discontinuation of Tab Groups (Panorama) - #9 by dietrich (2015-11-10) and from your GitHub - autonome/Tab-Groups: Reimplementation of Firefox Tab Groups as an add-on I see that you are, or were, a user of Tab Groups.
Your recent 1,691 tabs use case is widely appreciated for its focus on performance, but there’s no sign of grouping:
If not Tab Groups, then what now do you use?

Today: 906 tabs in seventy-six groups across thirteen windows.
Tab Groups with Firefox 56
First impression, after a few hours with 56.0 on FreeBSD-CURRENT:
- occasionally, a switch from one group to another is ineffective.
Workaround:
- switch away from the required group, then back to the group.
Gut feeling: it’s not an issue with Tab Groups. More likely an undefined side effect, or after-effect, of other issues that I observed today.
Postscript
I forgot, I added layout.css.servo.enabled as true in readiness, whilst still on 55. Today I changed it to false (the default); maybe the Tab Groups switching issue will not recur. A long shot.
