I love the MRU order of the Ctrl+Tab feature of Firefox. Actually, this was the reason why I returned to Firefox after using a competitor for two years. (Vivaldi's MRU feature is buggy, most of the other browser don't have this feature at all or they have other issues.)
When I press Ctrl+Tab in Firefox, I can see the 7 most recent tabs only. If I want to go back to the 8th or 9th, etc., I cannot do that. There is the "List All 672 tabs" button but it shows the tabs in the same order as the tabs appear on the sidebar, so it doesn't give any extra help.
I think if I click the "List All N tabs" button, they should appear in their Most-Recently-Used order, not in the order how I created them.
Could you change this, please?
