Every few days Firefox says all connections not secure

Every few days or so (even if I have rebooted in between) Firefox error says connection is not secure and I cannot access any web page. The error says 'the owner of __________________ has configured their web site improperly .......' Some of the sites: facebook, microsoft, google, mozilla,

I have tried some of the solutions to previous questions: Clearing cache, restarting firefox, starting in safe mode with add ons disabled. I also tried disabling AVG, turning off firewall, resetting wireless adapter and none of those worked either. Once I reboot the PC, then everything is working (even without trying any of the above fixes and with firewall and AVG active) This all of a sudden appears and I'm not always on the same page when it happens.

HI let's try this please : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

Reinstall with Current Release Firefox 59.0.3 with a Full Version Installer

Please let us know if this solved your issue or if need further assistance.

I will try this this afternoon. I should have mentioned this is a new (to me) system and everything has been freshly installed less than two months ago (including the OS fresh clean install on a wiped HD) and Firefox was a fresh install then.

When you see that error page, could you click the "Advanced" button and look for an error code in ALL CAPS, it often starts with SEC_ERROR.

This article discusses the most common of those codes: How to troubleshoot security error codes on secure websites.

If that doesn't point toward a solution, could you click the error code in the page to see whether that opens a panel provided a coded version of the certificate that Firefox doesn't trust? There should be a button to copy the large block of gibberish, and then you can paste it into a reply here.

I tried all those solutions and it gives no option to view the certificates. Also says cannot add exception. Will have to wait until it happens again before I can try anything more with it --- just happened again right before I posted so that may be 1-3 days or so before it happens again (if the other solution above does not work)

True, you cannot add exceptions if a site requires "strict transport security." However, you usually can click the error code to get at the certificate information; sometimes it's not there.

For future reference if the problem recurs:

If you cannot access the coded certificate on a "strict" site you may need to investigate using a different site that is a little less strict with its security. For example:

https://www.userchrome.org/

Do you get the error there?

Assuming so: click the Advanced button, then click the "Add Exception" button (see first screenshot below). We're not really going to add an exception, but we can get a better view of the certificate here.

In the Add Exception dialog, click the "View" button to pop up a certificate viewer. The interesting part is the "Issued by" section. I've marked that on the second screenshot for reference.

On my site, the "Issued by" section shows me "Let's Encrypt Authority X3". What do you see there?

(These example screenshots are from a test page, not my site)

NO - I click on to report to mozilla and it leads to the error page saying mozilla is an insecure connection. It also states exception cannot be added (screen shots added in OP - will re-attach one on this)

OOPS - that was not the right one --- see the screen shot in this post

But if you click the "Advanced" button next to the blue button, does it open a panel with more error details? If checking that box is breaking how the Advanced button works, please uncheck it.

I am using firefox now and it is currently working. I did try to uncheck the box and still could not get it to work. I tried all the previous solutions related to this. Next time it breaks, I will take more screen shots --- when it breaks, it happens on ALL sites even the current ones I'm on and signed into. I cannot force it to break it just happens suddenly when I refresh a page or click a link and get the error - and once it breaks, I get the error on all pages.

Just happened again. Took screen shot with it expanded and clicking on 'dvanced' only shows the certificate and gives you the option of copying it to clipboard (below)

Thanks, the coded certificate has this issuer info:

AVG Web/Mail Shield Root
generated by AVG Antivirus for SSL/TLS scanning

Which raises the question, why would Firefox keep losing track of the AVG/Avast signing certificate used to generate the fake site certificates necessary to intercept and filter your browsing? Once Firefox is set up, usually it's stable unless you use the Refresh feature.
