Single window most of the time. I tend to keep the number of tabs open at 12-20 tabs. As soon as the tabs become too many I often rearrange them keeping only the ones I still need, and close all of the remaining tabs. There was a point in time where I tended to keep tens or even hundreds of tabs open but I eventually realised that doing so was pointless. I still have a bookmarking ritual though, where I bookmark anything and everything that is even the slightest bit interesting. Maybe one day I will be able to kick that habit as well. The only plug-in I really care about is uBlock Origin on Firefox and Chrome. On my own computer I use Brave browser which has ad-blocking built into it. Yes, we can be friends.
