Benjamindaines said:What browsers are those?
In 1992, there was pretty much only Mozilla, wasn't there? I think Netscape came out in 1994 or 1995, right?
But I think Opera has had tabs for a long time. And Mozilla's main browser, predating Firefox, has been around for a while with tabs, too. And, I guess, several of the Linux browsers, such as Konqueror.
I don't know who's first, but I don't think it's Safari.
