Everything which is done in gBrowser.removeTab should be considered carefully. Reproducible: Always

Something done in gBrowser.moveTabTo should also be considered, such as ensureElementIsVisible.

Is this just for code cleanliness purposes? Or are you asking for a functional change? Raymond did you make these changes in tabbrowser? Can you investigate?

This is requesting moveTabToGroupItem to have its behavior fixed like removeTab (from the tab bar). I'm not sure whether this is a functional change.

See patch for bug 608184, I think it fixes this as well.

(In reply to comment #4) > See patch for bug 608184, I think it fixes this as well. tab.owner issue seems correctly handled. Other issues should remain.

Panorama has been removed from Firefox 45, currently in Beta and scheduled for release on March 7th. As such, I'm closing all existing Panorama bugs. If you are still using Panorama, you will see a deprecation message in Firefox 44, and when 45 is released your tab group data will be migrated to bookmarks, with a folder for each group. There are also a few addons offering similar functionality. See https://support.mozilla.org/en-US/kb/tab-groups-removal for more info. We're removing Panorama because it has extremely low usage (about 0.01% of users), and has a large number of bugs and usability issues. The cost of fixing all those issues is far too high to justify, and so we'll instead be focusing our time and energy on improving other parts of Firefox.
