When I middle-click a link in Firefox, I would like the new tab to open adjacent to my current tab, not all the way at the end of the tab bar. How can I make this happen in Firefox 7?

There is an option you can set. Go to the address bar, and type about:config

After you click Ok on the warranty warning, do a search for this config setting, double click it to say true.


  • Huh. For some reason this was set to the non-default of False in my browser. I'm pretty sure I never set it that way. Setting it to true fixed my problem. Thanks! Oct 13, 2011 at 21:26

7 years later.

Firefox version 63.0.3 (64bit).

browser.tabs.insertRelatedAfterCurrent is default true now.

And yet, to get [Ctrl+T], and the [+] button (to the right of the tabs), to open a new tab to the right of the current tab, instead of to the far right of all tabs, I set

browser.tabs.insertAfterCurrent to true (by double-clicking this boolean preference).

It was default false.

I believe [Ctrl+click] and [right-click -> open in new tab] follow the behavior of the first-mentioned perference, browser.tabs.insertRelatedAfterCurrent, because they are "related" because you clicked on the current page to get to the new tab, and on the other hand [Ctrl+T] and [+] follow this new preference, browser.tabs.insertAfterCurrent, becaused they are new (blank) tabs, and so unrelated to the current tab.

(Note one preference has "Related" in its name, and the other doesn't.)
