Images or elements don’t appear online in firefox
This isn’t a bug report. I’ve posted this as a reminder to myself and in the hope that it helps to prevent anyone else wasting the time I’ve just wasted trying to fix a non-existant problem. For the last hour I thought I was looking at a Firefox 3 bug which was making an element not appear in the online version of a site. Everything seemed fine offline but when i uploaded the files the element just vanished. The answer? disable ad-blocker extension. Due, probably to the image dimensions or the items ID, my ad-blocker had kicked-in causing a particular image to disappear.
Hope this saves people some man-hours.
