🗣 Wd提问: dns firefox

🤖 Ai回答:
It sounds like you're interested in DNS settings or issues related to Firefox、Here's some information that might help:

1、DNS Settings in Firefox:
Firefox uses the operating system's DNS settings by default.
However, you can change the DNS server used by Firefox by going to `about:config` in the address bar and searching for `network.trr.mode`、This setting is related to Trusted Recursive Resolver (TRR), which allows Firefox to use DNS over HTTPS (DoH) for improved privacy and security.

2、Using DNS over HTTPS (DoH):
To enable DoH in Firefox, you can modify the `network.trr.mode` preference to 2 or 3 in `about:config`.
Setting it to 2 will activate DoH but only if your current DNS server doesn't work.
Setting it to 3 will force Firefox to use DoH even if your current DNS server works fine.

3、Troubleshooting DNS Issues:
If you're experiencing DNS resolution issues, you can try changing your system's DNS servers to public ones like Google Public DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1).
In Firefox, you can also clear the DNS cache by navigating to `about:networkingdns` and clicking Clear DNS Cache.

If you have a specific question or issue regarding DNS with Firefox, feel free to provide more details!
