some web pages leave out the left and right area of the screen? On this page Mozilla support https://support.mozilla.org/en-US/kb/websites-look-wrong-or-appear-differently#w_clear-the-cookies-and-cache and on my fetlife.com web page the left and right of the screen is empty. I disabled all add blockers, have not antivirus on, zoomed in and out, changed the font size but all that does is make the letters load on top of them selves not make the page do full screen.
