DNS requests through a SOCKS proxy when the proxy server does not support DNS causes the connection to hang

[tom-HCgY7HY6kq]

Before submitting a bug report

• [x] I updated to the latest version of Multi-Account Container and tested if I can reproduce the issue
• [x] I searched for existing reports to see if it hasn't already been reported

Step to reproduce

1. Create a SOCKS proxy server without a DNS server configured
2. Create a FF container configured to use the SOCKS proxy on either socks:// socks4://
3. Load a webpage in the container

Actual behavior

DNS resolutions being attempted through the SOCKS proxy cause the connection to hang.

Expected behavior

It should be possible to optionally disable DNS requests being sent through the SOCKS proxy.
