"This Connection is Untrusted" error message. FF keeps searching for https instead of http. What is the fix?

Since Monday, websites that I have visited for years are now all of a sudden giving me this message. I notice that when this message pops up, the address bar is normally displaying "https" instead of the usual "http", I remove the s and sometimes it does not work and reverts back to "https". It is even affecting my search on google images where no pics show up at all. When I search in "Safesearch" the images show up but not any other time. I don't have this problem in other browsers just firefox, and only on my laptop not my desktop and both are running the same ESET security system and firefox versions. I have re-installed firefox but that does not fix the problem.

can you try to disable ssl scanning within your eset security program & see if the problem continues?

Hello,

Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache. Note: This will temporarily log you out of all sites you're logged in to. To clear cache and cookies do the following:

  1. Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
  2. Under "Time range to clear", select "Everything".
  3. Now, click the arrow next to Details to toggle the Details list active.
  4. From the details list, check Cache and Cookies and uncheck everything else.
  5. Now click the Clear now button.

Further information can be found in the Clear your cache, history and other personal information in Firefox article.

Did this fix your problems? Please report back to us!

Thank you.

Philipp, thanks for responding. I just tried to go to ebay and this is the error message: signin.ebay.com uses an invalid security certificate.

The certificate is not trusted because no issuer chain was provided.

(Error code: sec_error_unknown_issuer)

Same message when trying to access Facebook.

Philipp, it works! Thanks so much to you and Amit. Do you know why this all or a sudden became a problem?
