Does this work or do you need screen shots?

thanks - nothing obvious there. could you try disabling ssl scanning in avast like explained in How to troubleshoot security error codes on secure websites and see if this can make a difference?

I followed the directions and then closed my browser and reopened it. The problem is still there.

Before proceeding with the below steps, I suggest you check your internet connection. Ensure you have a workable speed.

Next, go to Options, navigate to Privacy, click on remove individual cookies and then hit on clear all cookies. Try Loading the page again, If you have same problem then follow with the next set of steps.

Click on ALT key on your keyboard, navigate to Help->Troubleshooting. Now click on refresh Firefox. Try loading amazon and Facebook again.

Hope this helps!

Removing the cookies worked for the Amazon site. Thanks!

I followed the 2nd set of instructions for facebook. When I opened my browser again Firefox asked about updating my setting or importing settings maybe and then I got a screen that said success! When I try to visit any pages now I get an error page that says "Your Connection is Not Secure". The Error Code under the Advanced button is " SEC_ERROR_UNKNOWN_ISSUER" I am using Chrome to respond to you because I can't pull up anypages on Firefox right now. I don't know if refreshing helped with Facebook or not. Is there an easy fix to this Error Code?

Update: I closed out of Firefox and reopened it. This time I was asked to choose a profile. I pulled up my old profile before I hit refresh Firefox and it still works fine. Amazon works, but not Facebook.

I closed Firefox again and opened the new profile that was created after refreshing Firefox and it will not let me pull up any pages saying my connection is not secure.

Should I go back to my old profile?

in the new profile please try this to give us more information about the error: on the your connection is not secure page, click on the advanced button, then on the error code, copy the text to the clipboard (like shown in the screenshot) and then paste it here into a reply in the forum.

thank you!

thank you - so it appears to be the qustodio parental control software that is running on the device and intercepting secure connections that will cause those issues...

Do you have this issue with multiple websites? Try www.gmail.com , www.outlook.com. Kindly send a screenshot of the same while you are trying to access. Also can you say the exact time that is shown on your watch/clock and not on your PC.

Phillip, thank you for the tip on Qustodio. Is it causing the problems with the Error Code or Facebook or both? Also, if it is with the Error Code any ideas why now after the refresh and not before?

Akash, the time on my clock is 10:03 am.

Which issue are you referring to? The facebook and amazon problem or the Error Code in Firefox after the refresh?

SOLVED! I removed my user profile on Qustodio and closed my browser. When I reopened I chose the Firefox profile created after the Firefox refresh. Amazon and Facebook work now and I am not getting any Error Codes. Thank you Phillip for your help! Your advice to remove the cookies and refresh Firefox worked great! - Qustodio just complicated things.
