This Connection is Untrusted on every site
Hi there, I have this come up on every site. Some background:
1. The error is always 'no issuer chain was provided' (Error code: sec_error_unknown_issuer) 2. My time and date and time zone are right 3. I have tried deleting the cert8 file, no change 4. I have followed the instructions from Microsoft regarding the 'Family Safety Certificate' which didn't work as it did not appear in the place the instructions directed me to. 5. I am using a brand new laptop (purchased today) and downloaded Firefox today so everything is up to date. 6. I only had McAfee security which I uninstalled to see if that was the issue, but it is still occurring.
Please help me I am at a loss, and I have to use Firefox for Uni.
Thanks

Create a new profile as a test to check if your current profile is causing the problems.
See Creating a profile:
- https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
- http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem

Thanks iamjayakumars, but those didn't work. Any other ideas?
hello Sarahlea1983, can you check and report back who's the issuer of the certificates - see screenshot:
