Firefox won't login?

Firefox will no longer let me login to lots of websites including Delicious, Facebook, eBay and Abbey (Bank Account). Safari is ok.

For any website where the login boxes are on the main page like Mac-Forums it's ok but for sites where the 'Sign In' or 'Login' is a link Firefox will not go to that link.

In Firefox/Preferences/Privacy I have 'Accept cookies from sites' ticked (I've checked 'exeptions' and above sites are not listed). I also have 'Accept third party cookies' ticked.

This has only started happening a few days ago. Before that everything was fine.

I have recently re-installed 'Little Snitch' - could this be the reason?

Any help much appreciated.

You got it ion one with Little Snitch. Have a look at this link and do a Google of Little Snitch and Firefox/Safari and then unsnitch?

TidBITS - Little Snitch

Thanks for that.

Just had to allow Firefox access via Little Snitch configuration.

I should have known that!
