Firefox not loading images from a specific domain

[Nikkiru]

I'm having a problem with FF not loading images from one specific domain. Every other domain I've tried loads images normally, but somehow I've blocked this specific domain. I've asked other users of the domain, but nobody else seems to be having this problem. I can also load images from this domain in other browsers, and I've already checked the hosts file anyway, so it doesn't seem related to that.

I also didn't find anything relevant when I searched for the domain name and IP on the "about:config" page. I also looked at tools > options > content to see if I had any exceptions under "load images automatically", and I didn't.

I just installed FF3, but this problem started before I did that.

Moving to Firefox Support as no specific bug has been identified here.

What is the URL of this problem site?

1:
You can start Firefox in Safe mode to check if your problem is caused by an extension or theme (try the DEFAULT theme).
If starting in Safe-mode works then disable your extensions (Tools > Add-ons > Extensions or use the option in the Safe-mode window) and re-enable them one by one until you find which one is causing it.
Close and restart Firefox after each change.

2:
You can try to create a new (test) profile to check if it is caused by your current profile.
See Standard diagnostic: Profile issues
First test the new profile without making changes and if that works then you can transfer some files to the new profile or you an try to fix the original profile. Be careful that you do not copy corrupted files.
