• Does this only occur with Firefox?
• Has it only happened after a Firefox update, or changes to your security related software.
  • What security related software is in use ?
• Does it happen repeatedly and reproducibly only for certain sites ?
  • or does it appear fairly random and sometimes working sometimes not; even for the same site

Do any of these help

1. Firefox can't load websites but other browsers can
2. Firefox and other browsers can't load websites
3. Websites don't load - troubleshoot and fix error messages
4. Server Not Found - Troubleshoot connection problems
5. Configure firewalls so that Firefox can access the Internet
   • How to let Firefox use the internet on your Windows computer

This is a problem that could have a number of causes. The third article linked above lists some of these and offers advice in tracking down and fixing the problem.

Check the connection settings.

• Tools > Options > Advanced > Network : Connection > Settings
• https://support.mozilla.org/kb/Options+window+-+Advanced+panel

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":

Thanks, I found it only happens on one website "OLX". I checked connection settings. See attachment please.

Further to my original post i now find that if i google olx it loads ok for me but when i click on the olx bookmark it gives me the oops message.

Just delete the existing bookmark then, and make a new bookmark from the page that works.

I deleted the old bookmark and did another but it works occassionally and not all the time. I can google "OLX" free ads and it works from there.

All of my bookmarks for sites work ok. i.e. when i click on any other bookmark the site opens ok.

What is the bookmark ?

Paste the link into your next message. I will see if it works for me.

That is caused by the server response:
