Starting Firefox

First, note that I uninstalled Malewarebytes, and rebooted. When I try to start Firefox, I get:

Secure Connection Failed 

         An error occurred during a connection to www.malwarebytes.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 website owners to inform them of this problem. Alternatively, use the command found in the help menu to report this broken site.

Any clue?

Is that the only site giving you problems?

Could you check your connection settings here:

  • Windows: "3-bar" menu button (or Tools menu) > Options
  • Mac: "3-bar" menu button (or Firefox menu) > Preferences
  • Linux: "3-bar" menu button (or Edit menu) > Preferences
  • Any system: type or paste about:preferences into the address bar and press Enter/Return to load it

In the search box at the top of the page, type proxy and Firefox should filter to the "Settings" button, which you can click.

The default of "Use system proxy settings" piggybacks on your Windows/IE "LAN" setting. "Auto-detect" can lead to a flaky connection. You may want to try "No proxy".

Any improvement?

More generally:

When I visit and check Page Info > Security (Ctrl+i), it shows the site uses TLS 1.3, which is a bit unusual, I think. Most sites use TLS 1.2 for backwards compatibility. However, there should be no problem connecting to TLS 1.3 sites in Firefox 88.
