Firefox Panorama, the cool tab-organising feature we've loved since its creation, has changed up its shortcut and added some new ones allowing you to switch between tab groups with a hotkey (and without opening the Tab Panorama window).
Reader Minibeardeath explains:
I just discovered that in Firefox 4, if you use the tab groups (Ctrl + E) then you can switch between groups using Ctrl + ` and Ctrl + Shift + ` in the same way you would use Ctrl + Tab to switch tabs.
So, not only has the main shortcut changed, but you can now cycle through groups with a few keystrokes. They're strange key combinations to be sure, and ones we probably wouldn't have found ourselves, so we thought we'd share with all of you that are taking advantage of this feature in the newest Firefox 4 betas. Note that, while the main Tab Panorama shortcut is different in OS X (Cmd + E instead of Ctrl + E), the group cycling shortcuts are the same on all operating systems.
