I just closed some tab groups, came out of panorama, and then realized I shouldn't have closed two of the groups. There does not seem to be any way to get them back though. This is contrary to the History > Recently Closed Tabs and History > Recently Closed Windows functionality. Panorama should really have the same sort of thing. As an aside, when I closed the groups they changed to a little area saying Undo Close Group, so I thought going back to undelete wouldn't be a problem. Those areas had gone though. Subsequently I found that they disappear after a few seconds. I think this is really bad. There's a small (x) on them to close them if you really want them gone, and I really dislike this timeout behavior.
Seems like this bug is two ideas. 1. Make undo close group more coherent with the undo close tab and history features. and... 2. Get rid of the timeout on our current undo close group in Panorama I am a big fan of 1; if we can (and we clearly can) keep track of your groups, then Firefox should reflect that in a more unified manner. I do not agree with getting rid of our timeout however. If we do that, we are essentially opening a modal dialog every time someone closes a group asking if they are sure. Also, if we implement part 1, then this is entirely unnecessary.

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.

Well I also missed that "tab groups" actually do exist, until I was looking for the keyboard shortcut to find a specific tab. Maybe that's one reason why few people use it (they don't know it exists). The other thing is that many people are completely unable to work with multiple windows (those who always have one window full-screen, as opposed to those who have windows all over the desktop) plus current incompleteness of the concept. This doesn't mean people don't use it because the concept is bad or not wanted; it's like the E-cars (i9nteresting, good, but not ready for mainstream) MHO...
