Cannot load certain websites/send mail

[anscan]

This one is driving me crazy.

I have certain websites that just hang whenever I enter an area requiring a login. For example it happens when I log in to Facebook, or certain areas of Yahoo. It happens on both Safari 4.0.1/4.0.2 and FF 3.5. It's always the same, it just times out and then I get a message along the lines of "server reset the connection".

I also cannot send messages in Mail using the Yahoo server (smtp.yahoo.co.uk) even though Connection Doctor tells me I can connect fine. I'm convinced this is linked to the problem above.

I have a PowerMac G5 (Dual 2.3GHz PowerPC) and a current model MacBook Pro, both using 10.5.7. They are synced via MobileMe, and both experience the problems described above. Meanwhile my wife has a MacBook which experiences none of these issues even when visiting the websites using my login details, and working on the same wireless network/broadband provider.

I have tried clearing FF and Safari caches, I have tried deleting any cookies with Facebook or Yahoo in them, and I have tried deleting & recreating my SMTP server details, all to no avail.

Any guidance would be much appreciated!

Thanks.

Hi! Have you tried repairing permissions and then restarting, so you can restart your browsers and see if the problem persists? Often times repairing permissions is all that's required to fix these strange isolated issues.

Sounds possibly like either a java thing and/or a cookie thing in your browsers.

Run the free DNSChanger Removal Tool and see if you have one of those. Plus start using the free OpenDNS DNS servers (they work in Europe now too) to see if it helps.

lastly check to see if the built it firewall (disable it temporarily to check) if somehow blocking the SSL port.
