Personally I’m a huge fan of tabbed browsing in Firefox and now Internet Explorer, but for some reason people out there want to know how to disable them - so here you go;

Firefox

You need to install and add on from Mozilla called Tab Killer, by running this you will completely disable the ability to use tabs.

Download Tab Killer

Internet Explorer

  • Click tools > internet options
  • Click settings in the tabs section
  • Uncheck enable tabbed browsing
  • Click OK
  • Restart your IE
Disable Tabbed Browsing
