This page appears on startup It says UNABLE TO CONNECT Firefox can't establish a connection to server uk.yahhoo.com

. Unfortunately Firefox can't I can get to yahoo with IE

Hi again wrighly, I had hoped that my previous suggestion would work for you. I understand you seem unable to use the link

• uk.yahhoo.com

That does not work for me either in Firefox. It tries to use http://uk.yahhoo.com/ which is not a page Firefox can find and use. Did you try the link I provided, that works for me in Firefox to open a Yahoo UK page

• https://uk.yahoo.com <== Clickable link
  • Does that work for you if you click that link ?
  • If not please describe what happens and any error message.
    Please paste the full error message in to your reply.
  • Or please try to attach a screenshot of the error message
    Please see How do I create a screenshot of my problem?

If the link works for you it can be made in to your home page or one of your homepages for Firefox. or maybe used as a pinned tab,or tile if that is more convenient:

• How to set the home page
  • Home page with pipe character opens extra tabs when Firefox starts
  • Startup, home page, tabs, and download settings
• Pinned Tabs - keep favorite websites open and just a click away
• Customize your Firefox New Tab page

Removed Antivirus (AVG). Problem solved with Re-installation

Problem solved by removing and re-installing security (AVG)

Thanks for posting back. I will mark your post as the solution to the problem, that makes it visible to others including on external searches and it may help them.

I do wonder if your problem may be something similar to those mentioned in this help article.

• How to troubleshoot security error codes on secure websites

However that does not specifically mention AVG. Presumably AVG normally behaves well with Firefox and either yours was faulty or needing updating.
