While we are not an official Mozilla community, we have adopted the Mozilla Community Participation Guidelines as far as it can be applied to a bin.

Rules

  1. Always be civil and respectful
    Don't be toxic, hostile, or a troll, especially towards Mozilla employees. This includes gratuitous use of profanity.

  2. Don't be a bigot
    No form of bigotry will be tolerated.

  3. Don't post security compromising suggestions
    If you do, include an obvious and clear warning.

  4. Don't post conspiracy theories
    Especially ones about nefarious intentions or funding. If you're concerned: Ask. Please don’t fuel conspiracy thinking here. Don’t try to spread FUD, especially against reliable privacy-enhancing software. Extraordinary claims require extraordinary evidence. Show credible sources.

  5. Don't accuse others of shilling
    Send honest concerns to the moderators and/or admins, and we will investigate.

  6. Do not remove your help posts after they receive replies
    Half the point of asking questions in a public sub is so that everyone can benefit from the answers—which is impossible if you go deleting everything behind yourself once you've gotten yours.

Firefox is nuking NextDNS with over 20k queries a day. (lemmy.fmhy.ml)

I tried giving NextDNS a shot. So far it looks great. My only problem it has 300k query limit for free in a month. I tried investigating the source of problem by looking a bit into about:networking and found out many queries has time to live of 300 seconds. I tried turning nextdns cache boost off and on but it made no difference. In order to reduce number of queries i send i set network.dns.get-ttl false (i don't know if it relevant since i am using DNS-over-https), network.dnsCacheEntries 1000, network.dnsCacheExpiration/network.dnsCacheExpirationGracePeriod= 43200. While this setting sometimes apply to one or two queries occasionally it was pretty much ignored most of the time. I am on windows 10 and using arkenfox user.js. Does anyone have any idea how i can force a higher ttl on dns cache?

We recommend not using arkenfox user.js, as it can cause difficult to diagnose issues in Firefox. If you use arkenfox user.js, make sure to read the wiki. If you encounter issues with arkenfox, ask questions on their issues page. They can help you better than most members here, as they are the people developing the repository. Good luck!
