Does FF send DNS requests via the proxy? Depending on the personal threat model and the ISP, that might matter.

FF defaults to DNS-over-HTTPS now, so I would imagine it does, although I can't find solid confirmation.

Only in the US.

There are checkboxes to control this in the Firefox proxy settings. "Proxy DNS when using SOCKS v5" and "Enable DNS over HTTPS".

In the proxy options, there's a box to tick for sending DNS through the proxy or not.
