Secure Connection Failed - Nothing helps
Error: "Secure Connection Failed
An error occurred during a connection to accounts.firefox.com. Cannot communicate securely with peer: no common encryption algorithm(s).
Error code: SSL_ERROR_NO_CYPHER_OVERLAP
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the web site owners to inform them of this problem."
When it happens: - Irregular frequence. The same websites once work once don't. They work with Chrom/Edge/From my mobile(same wifi/router). - Sometimes I have to refresh the page a few times - Happens for all sort of webistes. From local news, to GitHub/Youtube/Google/Any website
Steps I have taken: - Cleared cache/cookies - Reset PC/Firefox - Cleared all extensions - Deleted Firefox (And manually deleted all folders in AppData related to Firefox) and reinstalled afterwards
Nothing helped. Any idea what is going on? I checked Mozilla documentation for SSL issues, but it didn't help either

It happens even to this support website and it doesn't always load from my PC/firefox. It does work on other browsers.
You can check your browser.
Are you using a proxy or VPN?
You can check the connection settings.
- Settings -> General -> Network: Connection -> Settings
If you do not need to use a proxy to connect to internet, select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.
See "Firefox connection settings":
Boot the computer in Windows Safe Mode with network support to see if that has effect.
