All sites are "Connection is Untrusted", does not exempt, and then improperly loads pages.
I have no security on my computer, my time/date is synchronized and this just started about two days ago.
Every site pops up with this as the description in details:
The certificate is not trusted because no issuer chain was provided.
(Error code: sec_error_unknown_issuer)
When I try to add the site as an exception it either doesn't work, doesn't accept it for other pages, and when it does let me go on the entire page is loaded wrong and useless (like facebook and youtube). Can someone at least point me in the right direction to solve this? I've tried having Firefox not ask for permission but the message still pops up. I've tried resetting it with nothing done, as well as uninstalling and reinstalling Firefox.

Hello,
Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
(If you're not using it, switch to the Default theme.)
- You can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
- Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.
Once you get the pop-up, just select "'Start in Safe Mode"
If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.
To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.
Thank you.
Check out why the site is untrusted (click "Technical Details to expand that section) and if this is caused by a missing intermediate certificate then see if you can install this intermediate certificate from another source.
You can retrieve the certificate and check details like who issued certificates and expiration dates of certificates.
- Click the link at the bottom of the error page: "I Understand the Risks"
Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".
- Click the "View..." button and inspect the certificate and check who is the issuer.
You can see more Details like intermediate certificates that are used in the Details pane.
If "I Understand the Risks" is missing then this page may be opened in an (i)frame and in that case try the right-click context menu and use "This Frame: Open Frame in New Tab".
Try to rename the cert8.db file in the Firefox profile folder to cert8.db.old or delete the cert8.db file to remove intermediate certificates that Firefox has stored.
If that helped to solve the problem then you can remove the renamed cert8.db.old file. Otherwise you can rename (or copy) the cert8.db.old file to cert8.db to restore the previous intermediate certificates. Firefox will automatically store intermediate certificates when you visit websites that send such a certificate.
If that didn't help then remove or rename secmod.db (secmod.db.old) as well.
Check and make sure you don't have anything that re-directs. I had something called Sendori installed and i also read someone had kaspersky, and that was re-assigning certificates which was also causing problems.
I just had a computer that was doing this and I finally figured out what it was.
This was an older PC and the clock battery on the motherboard had gone bad - so it was resetting the clock to a date in 2004 - so all the certificates weren't valid UNTIL 2013.
Reset the time, replace the battery and problem solved.
Check the time of your system. If it's wrong then set it, all problems would be solved by then. :P
