From the unsure why you’d want to do this department comes this tip on how to completely disable tabbed browsing in Firefox. I’ve gotten quite a number of requests for this over the last few months, so I’m finally breaking down and writing an article about it.
It’s extremely simple, actually… just install the Tab Killer extension which will remove every trace of tabs from your Firefox. If you middle-click on a link, it’ll open the link in a new window instead of a new tab.
Look, no tabs!
This is probably useful if you are trying to convert somebody that is used to IE6 and doesn’t understand the concept of tabs.
