I have Firefox 3.6.9 (on XP pro) set to ask me every time and block third-party cookies. Despite this I noticed that both live.com and yahoo.com (neither of which I visit directly) were able to leave persistent cookies. Having noticed this I blocked both sites using the method in the header. This did not work.

I only managed to block them by visiting the sites and using Page Info > Permissions.

It would be nice to know why this can happen. Thank you.

Maybe one of the cookie related extensions is causing that problem.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

Thanks for that cor-el. I haven't got any cookie related extensions enabled, and it happened in Safe Mode.

I haven't got the problem any more as I explained, I really wanted to know why an apparently blocked third party site was able to bypass the block.
