I remember a time when #browsers only supported having a single page open at a time. It wasn't that long ago; I could be wrong (please correct me if I am), but I think #Chrome was the first to offer tabbed browsing, and then the others following suit.
Was #IE7 the first version of #InternetExplorer to support it, or was it supported from #IE6 already?
I started my working life when #IE3 was still the standard, and I remember being astounded along with everyone else at the advent of #IE4 and the Active Desktop. Remember the Active Desktop? You could carve out pieces of websites and put them on your desktop and have them refresh automatically. People used it for news feeds (social media wasn't a thing yet) or weather reports or even just to show the time.
*sigh* These are just more things that the #GenZ generation will never understand. Along with the fact that not all #GIFs are animated (in fact, in the old days, very few of them were because adding extra frames took up unnecessary disk space and bandwidth).
