Unable to ser IPv6 proxy IP

[wildnet]

• Multi-Account Containers Version: 8.0.2
• Operating System + Version: Ubuntu Linux 21.10 amd64
• Firefox Version: 94.0
• Other installed Add-ons + Version + Enabled/Disabled-Status:

Actual behavior

When I try to user proxy in container, I'm able to set only IPv4 address [ ie.: socks4://127.0.0.1:1080 ]

Expected behavior

use IPv6 proxy address [ ie.: socks4://[::1]:1080 ]

Steps to reproduce

1. use some IPv6 ( ie.: SSH .ssh/config DynamixForward [::1]:1080 ) not necessary because problem is with interface
2. try to set advanced proxy settings address ( socks4://[::1]:1080 )
3. Error message will shows "Please enter a valid proxy URL"

A year later, this is still an actual problem.

It also seems a simple fix:

Source for the regex.
