Chrome, Firefox, and Vivaldi.
Chrome for most things because the interface is nice and tiny.
Firefox for youtube and stuff that Chrome turns super slow.
Vivaldi only when I've opened too many tabs and want a separate browser to separate things.

I used to just strictly use FireFox, but then I started using Chrome for duel browsing when I wanted to use two accounts on one site I used to be on. Now it's pretty much the other way around with Chrome being my primary and only for a couple things do I still use FF.

Once upon a time, I was known to occasionally view websites by assembling an HTTP request manually and reading the data as it came back.

Very few websites keep their HTML readable enough to make that feasible now for anything beyond debugging the protocol stack.

I've also been known to send and read e-mails that way, and I still occasionally do it for IRC chats.
