I thought I'd ask the computer geeks for help. I use Linux OS & Firefox 3.6. Something is wrong with my laptop, it has been acting up all night. Ever since I went on Crowdflower to vote on BYC calendar pics, I keep getting this error message: "secure connection failed, xml.freecause.com:443 uses an invalid security certificate. Expired certificate". I x out the message and it keeps popping up, it won't go away. So I munis it down. But I can't login to my email (Yahoo) or to FB. BYC is the only site I can get on. Can you help me? I am trying to upload pics to FB, and I can't.
