Site Shows Differently in Firefox

[Satch]

Greetings,

Tonight, April 19,2018, the site shows differently in Firefox on my Windows 10 PC. I cleared History and Cache. No change. Microsoft Edge looks normal. The site in Firefox looks like a watered down Mobile version. I attached a picture.

I clicked on "Full" at the bottom of the page and it's back to normal. Don't know what I clicked to get the "Moble?" version in the first place.

At the very bottom of the page, on the far left, there is a little box. it says 'ws2016'--- If u click it open, options are revealed. One of them is 'mobile'---but there are others.

My kitty cat walked across my laptop one day, and when I looked at the screen, it was like I went down a rabbit hole. Everything was totally different---different colors, shapes, fonts, totally weird---I thought they redid the entire forum.

I posted about it, and someone told me about the little box in the bottom left hand corner....
