Getting a security error after some time when on common networks
Firefox works fine for an hour, but then I get the SEC_ERROR_UNKNOWN_ISSUER error after a while when trying to access Youtube, Twitch and some wiki pages. The only thing that helps is restarting the computer but that only lasts for a short amount of time.
Here is the error code to help (this one is for youtube):

Hi, https://support.mozilla.org/en-US/kb/troubleshoot-SEC_ERROR_UNKNOWN_ISSUER
There is security software like Avast and Kaspersky and BitDefender and ESET that intercepts secure connections and sends their own certificate or that incorporates special web shielding features that can block content. If this is the case please update your software and also check their Community Forums for Answers.
Always be cautious when you get an 'Untrusted' error message never create a permanent exception without investigating the cause and only use this to inspect the certificate
