Was Netscape the one that could run from the Comman Line, back in Win31 days? I can't remember, but I ~think~ my first forays were with Netscape 3.0... ?? Before that, I'd been doing a C-64 with bbs software.
In the meantime, I have been using Vivaldi for a few days now, and I do like it. It is very similar to Opera, but better. Like a cross between Opera and Firefox, only faster and seemingly more stable. No issues thus far. No bad page loads or anything. I don't know about their "security", but I haven't had pop-ups when going to some of the sites that will generate those in Firefox and / or IE11 (both with "pop-up blockers")...
