I'm facing a major issue with my website. Running on Mac OS with Firefox version 29 (and previous versions).
The site is responsive and built with Bootstrap. It functions perfectly on all browsers EXCEPT... On Mac using FF, right at the point where the media queries are supposed to change (e.g. max-width: 600px, resizing the window until the HTML element reaches exactly 600px in width), everything breaks (especially the divs with visible-xs and hidden-xs). This problem occurs at every media query breakpoint: 1025px, 1200px...
Any suggestions on how to resolve this?
