Things were mostly broken (i couldn’t get fluxbox to start) until i used tasksel to install Cinnamon so i could use a browser to look some stuff up (i only have one computer). I removed Cinnamon but whatever it left behind fixed my system enough that i’m now typing this in LibreWolf with not too many weird graphical issues. Some stuff doesn’t work at all yet, like my laptop’s function keys for things like brightness and volume.

So all in all, better than i thought this might go.

Thank you for that last bit. “Just do it” out to be the advice i needed.

That’s exactly what i was looking for. Thanks. I mostly want an easy way to make sure none of my web pages are too big, so looking in Developer Options makes sense.
