For the longest time I have not seen any site-content images on any webpage I’ve visited using Firefox on my PC. I cleared the cache’s, all internet files, restarted my computer, checked the Firefox settings.. all with no luck.
Finally I got fed up and did a Google search for “images disappear in firefox” and the first link suggests that it has to do with the Web Developer toolbar.
SOMEHOW I clicked on Disable All External Site images. Curse my geek side!
