All of a sudden I am getting loads of SPAM emails and when I try to unsubscribe, I get a Secure Connection Failed error. I have marked them as SPAM but they just keep coming, daily.

Hi, Since three or four months, whenever I log into Outlook live, either on Mac or Windows PC, I get a security warning saying that the information will not be secure (Please see attachment.) When I log into the same account, from Edge for example, I do not get the warning popup. I really enjoy using Firefox and would love to continue but this case is worrying me a bit. Any idea to help? Thank you very much, Mathieu B.

Did Not Connect: Potential Security Issue Firefox detected a potential security threat and did not continue to www.youtube.com because this website requires a secure connection. What can you do about it? www.youtube.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site. The issue is most likely with the website, and there is nothing you can do to resolve it. If you are on a corporate network or using antivirus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

If I try to log into my router at 192.168.1.1 I get a message that says "Warning: Potential Security Risk Ahead". I expect that, but when I click on the Advanced button it doesn't do anything. Works fine with Chrome, so not my router or anti-virus. ???

Here's what I've tried (none of these works):

   DNS over HTTPS turned off
   Uninstall all add-ons
   Reinstall Firefox
   Create new profile and set it as default
   Delete/rename certs.db in the Firefox profiles folder. 

I'm tired fixing errors which become more complex and solutions are written for people who have the time an knowledge to waste fixing these constant issues in FIREFOX, Time to change browser.

I don't know if this is relevant but one of the website that does not work is https://delta-executorr.com/

My laser printer will not print due to low toner. However, when I click on "more information" to find out the toner level, that site is shown as unsecure and cannot be accessed.

The connection to the server was reset while the page was loading.
