I use BarTab Heavy to unload tabs after a certain amount of of time. Which works I've tried letting the tab run out of time on its own or unload it manually and reloading it after that displays the site as intended. But when I use Firefox for some time, opening and closing tabs. Something happens that when I come back to the site so it wont display correctly. When I restart the browser it works fine again so I dont think its a issue with the sites themself. I've attached an image to illustrate the problem. In this particular case the images wont show. Even rightclicking on the position were they should be brings up the same context menu as if I'd clicked on an empty space on the page. Other sites show up even as blank pages. So far I've cleared cookies, cleared the cache and run through every troubleshooting solution I could find on the "Sites wont load pictures" topic. Nothing worked. I dont even know what is triggering the event, one time pages work fine the next not anymore.
