I installed the httpseverywhere add-on. I don't know if it has anything to do with the problem I am having but every time I try to access a page nearly all pages but not quite all I get a warning instead of what I am looking for. The warning reads This Connection is Untrusted You have asked Firefox to connect securely to... (some URL (the one on my screen now is "add-ons.mozilla.org")), but we can't confirm that your connection is secure.... The goes on with explanation of why this could be as well as what I should do about it. It then gives me a button that reads "Get me out of here" and a link "Technical Details" I have tried everything including resetting Firefox to its original settings, reinstalling Firefox, uninstalling and reinstalling Firefox. The computer is a Dell Latitude, I just upgraded it to Windows 10 and installed Firefox. Do I need to revert to Windows 7.1? How can I get my favorite Web browser back to usability?
Additional System Details
- User Agent: Mozilla/5.0 (Android 5.0.2; Mobile; rv:43.0) Gecko/43.0 Firefox/43.0
can you please give us the error code/information from the technical details section?
There is no Eric code. There is an icon of what looks like a security guard with the title given above. The rest of the text reads
Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.
What Should I Do?
If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.
This site uses HTTP stick Transport Security (HSTS) to specify that Firefox only connect to it securely. As a result, it is not possible to add an exception for this certificate.
The page then closes with the button and the link mentioned above.
what security software is running on your dell?
There is security software like Avast and Kaspersky and BitDefender and ESET that intercept secure connections and send their own certificate.
This Connection is Untrusted is sometimes caused because the computer system clock is wrong. Check the time / date / time zone settings.
I decided to go back to Windows 7.1, that solved the problem. Thanks all for your help!
Please flag your last post as Solved Problem so others will know.

If you can't inspect the certificate via "I Understand the Risks" then try this:
Open the "Add Security Exception" window by pasting this chrome URL in the Firefox location/address bar and check the certificate:
In the location field of this window type or paste the URL of the website.
- retrieve the certificate via the "Get certificate" button
- click the "View..." button to inspect the certificate in the Certificate Viewer
You can inspect details like the issuer and the certificate chain in the Details tab of the Certificate Viewer. Check who is the issuer of the certificate. If necessary then you can attach a screenshot that shows the certificate viewer.
