I'm not claiming, that it's a well thought out system. It's just what I do.

Closing windows is a thing I try to avoid, but if it happens, there's always my browser history that allows me to resurrect a few of them. (This is all happening in firefox btw. though I use different browsers on special occasions, for example if a website doesn't support the gecko engine very well)

I avoid closing windows because it still makes me nervous because this used to mean they were hard to recover and that fear is deeply ingrained in the back of my mind.

Using several windows is a way to keep tabs separated, because I lose track when I have to scroll through them. I could use tab groups for that, but meh... It also allows me to have them on different screens for stuff where I need to look up several things simultaneously.

sometimes I'm a bit overwhelmed by the number of windows though. But I'm too deep into it to change my habits. Wouldn't recommend it though.

All I'm saying is, that my PC doesn't mind at all.
