Dial Up. Yeah I know the sound and I know the time it took to load anything with. But it’s something I won’t ever miss having. I would much rather be on a 1MB connection if I had to choose between that or dial up ever again. I also hated how easy it was to be kicked off, if anyone called the phone, you were off it in seconds.
“Pop-up blocking” started out as a feature of specialty web browsers like iCab and Opera. If I recall correctly, Firefox was the first “mainstream” browser to build it in as a feature; and Chrome supported it from the beginning.
