It actually points directly to the answer: look at who is listed equally issuing the document for Facebook: Kaspersky.

Past any take chances did you lot utilize the Refresh feature during your last update? This can happen when Firefox reports it is starting slowly and says y'all can speed it upward by restoring some default settings. If you click the button, an Quondam Firefox Information binder appears on your desk with your old settings folder. Exercise you see anything similar that?

Reason I ask is, the old certificate file which was already prepare to piece of work with Kaspersky'south SSL Browse feature would be in there and you could re-create information technology over to your electric current settings folder.

Otherwise, y'all tin prepare Firefox up to piece of work with Kaspersky again.

I didn't update information technology, later on YEARS of having Firefox setup to not update on it'due south ain, information technology just did it. I have never had this happen before. In that location is now a folder on my desktop, as you described, but I never saw anything like you are describing. Anyway... I just had my reckoner guy look at it and he thinks he got information technology stock-still and cannot sympathize why the problem is But on my profile on this computer, none of the other profiles had this problem from the update. If I have whatever continuing problems I will be back here, and more set to delete Firefox. Thank you for the help.

What changed at Windows startup: the Kaspersky SSL Scan turned back on, or Firefox lost the authorization certificate and stopped trusting Kaspersky'due south simulated certificates?

If the problem is that Firefox lost the certificate, does the same problem occur if you get out Firefox and start information technology up again, or only when you lot close down and restart Windows?

Some utility software like CCleaner may change your Firefox settings files at Windows startup, but I don't know why any software would affect the cert8.db file. That seems strange.

the trouble is that your antivirus programme is intercepting all secure connections without being properly set-up to do then. this is looking similar a man-in-the-centre assault to the browser and therefore yous'll go the warning screens. if you want to troubleshoot the problem with us, and then please follow upwards on the questions asked/suggestions fabricated and go on your tone effective (otherwise this topic volition be locked). you can contact kaspersky's support likewise, you are paying for their product that is causing the problem!

Millions of Firefox users probably run Kaspersky, ESET, BitDefender or avast!, all of which practise the same kind of filtering and present faux certificates to Firefox. You definitely can make this work. Heck, you know that, considering it worked before you did the Refresh.

We would never suggest removing Kaspersky, so if you did, please reinstall information technology. Your security comes showtime.

Next, you tin can try to push Kaspersky'southward authorisation document into Firefox then Firefox trusts all of its imitation certificates, or you can plow off just the interceptions of your secure connections and keep all of the other Kaspersky features, your pick.

I have read through all of posts concerning this issue, and information technology is apparent to me that either a FF update caused this, or a Windows 10 update caused this. It is upsetting especially when I don't become the chance to override the fault msg. This never happened in earlier versions of FF, nor did information technology happen prior to my upgrading to Windows 10.

The only "fix" that works for me every time is to cut and paste the "offending" URL into Chrome. No problem getting to google.com or facebook.com. Therefore, after many, many years of using FF, I will be switching to Chrome until or unless this gets fixed.
