I switched to Firefox when Opera ditched Presto and mouse gestures were the thing I missed the most (along with windowed tabs). Took me a long time to stop trying to use them, those commands were etched deep in my muscle memory. I remember trying a few extensions but they never managed to replicate how smoothly it worked in Opera.
You can tell the Vivaldi devs care about that kind of stuff. I don't want to use a chromium-based browser as my daily driver, but I like a lot of what they're doing.
In the early 2000s, the biggest social media (though we didn't call it that back then) in Finland was IRC-Galleria (IRC-Gallery). It was originally made for IRC users to upload pictures of themselves and see what fellow IRCers looked like. You'd create a profile, add pictures and tag which channels/servers you were on.
Since there were no other websites like that back then, it was eventually overrun by non-IRC-users and transformed into what we'd now call a more generic social media platform. Something like the eternal September I guess. People started calling the gallery "IRC" as shorthand, which royally pissed off the original userbase. Fun times.
Then Facebook appeared and everyone moved there.
It's still up, but it's more of a historical relic these days. Not sure who, if anyone, still uses it: https://irc-galleria.net/
