Firefox some images do not show but they are correctly loaded if looking at firebug

I have some images that are not visible other are (background images or img tags indifferently ) If I check in firebug everything is fine, the image appears. It is as开发者_如何学JAVA if they were a display:none applied to certain images while other are perfectly ok. In Safari/Chrome everything is just perfect.

Does any one has met this problem already?

Brock Adams has helped me out. That was an issue with AdBlockPlus. The pin image not displaying is called Ads_pin_big.png and in ABP there is a rule blocking images starting with /images/ads_ ... So had Adams Brock advised me: "choose your image names wisely"

This has to be a problem with your cache. Clean it out, reboot your machine. CTRL f5 on those images. Should help.
