I have to access some services like Anyconnect on SSL port 993, 3389, etc, Chrome blocked it. I gonna use Firefox instead. So now today finally I got the solution, Enjoy and relax.

Solution

Go to chrome://flags disable this feature “Enable Network Service” to disabled , quit Chrome.

Create a shell under your Users directory and paste this into it.

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --explicitly-allowed-ports=993,465,110,21,22,3389

// give it permission
chmod +x unsafe-chrome.sh

Done

Firefox

  1. Go in about:config
  2. Paste network.security.ports.banned.override
  3. Type 0-65535 or specific ports that you allow to access.
