How to Force Firefox to Open New Tabs at the End

This tutorial will show you how to force Firefox to open new tabs at the end of the tab bar, rather than next to the existing open tab.

This behavior (opening new tabs next to the current one) was introduced way back in Firefox version 3.6 (it’s at version 88 as of this update). Some people like it, others don’t. If you fall into the “I want it back the way it was” camp – here’s how to change it.

  1. In the Firefox address bar enter about:config and hit enter.
  2. about:config in firefox

  3. Click the Accept the Risk and Continue button – we aren’t doing anything too risky.
  4. firefox about:config warning

  5. In the search bar, paste in the following:
  6. browser.tabs.insertRelatedAfterCurrent

  7. You should see line titled: browser.tabs.insertRelatedAfterCurrent listed (see screenshot below). Note that it’s value is set to true. Double-click on the word true.
  8. about:config browser.tabs.insertRelatedAfterCurrent displayed

  9. It should change to false (as indicated in the screenshot below).
  10. about:config in firefox with browser.tabs.insertRelatedAfterCurrent set to false

  11. That’s it! Close this about:config tab, and now when you click on links to open them in new tabs, the tab will be all the way at the end of your tab bar.

  1. Thank you Ross! I was going crazy with the change. Often, I work with a lot of tabs open – so when I open a link in a new one, it is easiest to find if it is at the end. What a relief!

  2. Wow thanks so much! I’ve been annoyed by this (default?) behaviour since I switched to 3.6 of Firefox.
