It could be facebook then, instead of chrome, or a combo of the two. I switched to Edge when I got a new work laptop, to see how I'd get on with it. Facebook was hideous, with funny spacings, but I thought I should persue it as Edge is meant to have some benefits on low end PC laptops using Intel graphics. I read a few comments about Fcaebooks new font in google searches. But a little after I noticed that facebook was fine. It had changed. I just checked again and it fine.
