My page view may be nonstandard, because I zoom in on most pages to favor my presbyopia. I don't see the link "(left of 'fix this')" to which you refer, and would appreciate tips on what manual changes to make in my own Facebook settings. Once you update that on your website documentation, I'll be sure to deep-link my friends to those same tips. Thanks.
P.S. Friendly general advice for web developers who use JavaScript elements that display on webpages: TEST those for users who have different font size settings or zoom settings to favor their own vision issues, lest links or other elements of your design overlap and become unreadable.
