Linux.

I retired the last Windows machine last year.

Firefox on Linux, though, is not working very well. It keeps hanging during long typing inputs. No CPU or disk usage, just stuck. And it uses so much memory that the OOM killer sometimes kills it.

I was never a Linux fanatic. It's just that I considered an operating system with ads unacceptable. I rather liked Windows 7.

Most likely is hardware specific (some driver bug).
