Toggle tabs in Zen Browser
I have been using Zen Browser for admin type stuff having moved away from Arc (after active development stopped) and missed the ability to toggle between tabs easily.
However, just a cofing tweak and life is slightly more pleasant moving between your current tab and the most recent tab used with a simple ctrl+tab. Or once you have pressed ctrl+tab, release tab and it will show the 6 most recent tabs in a switcher style list.
To enable go to…
about:config and search for…
browser.ctrlTab.sortByRecentlyUsed and toggle it to true.
Happy tabbing!
