Force links that open new windows to open in new tabs in firefox.

I’ve used Firefox for years mostly for the tabs. However, Firefox 2 removed the ability to “force new windows to open in tabs” and lately my number of “required” extensions have built up to the point that opening a new window takes 5-10 seconds. Which makes the occasional link that forces a new window very irritating.

To force all new windows into tabs type about:config in your url bar and set the following properties:

  1. ‘’ should be 3
  2. ‘’ should be 3
  3. ‘’ should be 0

    Thanks for that – it was really annoying me.

    This edit to the config did not resolve this issue for me. I have iGoogle as my homepage with widgets installed. One of those widgets is NPR and it will not allow a new tab or a new window to be selected from the menu for any of the links. Is there a way to force any and all links to open in a new tab or window regardless of how the Webmater wrote the page?.

    ‘’ to 0 as specified worked for me. open_newwindow already matched and I couldn’t find open_external.

    This was driving me crazy because I had one instance of FF on one machine that would open new windows in tabs and another instance a different machine that would not…despite all the FF options and addon options being the same that I could think of.

    This finally did the trick!
