Is there a shortcut key to switch back and forth between two tabs in Firefox?
For example, you can press CTRL + 1 to select the first tab, CTRL + 2 to select the second. What I want to do is switch between the current tab and the last selected tab. TV remotes have a similar previous or back button that does the same thing. If you only press this one button it will switching solely between two channels each time it is pressed. I see this is called a "last" button on TV remotes.
I know you can move a tab to be right next to each other as tab 1 and tab 2 and then use ctrl + 1 and ctrl + 2 but I'm talking about a switch shortcut.
I'm using Mac.
