My website www.gauravmittal.com is not showing correctly in Firefox. The images are showing up
as thumbnails below each other as opposed to large scrolling images. I have tried everything possible
from your available troubleshoot guide.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).
Do NOT click the Reset button on the Safe Mode start window.
I had the same problem with the following site http://livescores247.com I ran the browser in safe mode and it displayed correctly, without making any changes after switching to normal mode it was displaying correctly again!!
