Rules

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.

WebTransport is pretty exciting for folks who want to avoid the extra hassle of working with the lower-level WebSockets API, and it can also lead to better performance, so it could be a game-changer for some things; a surprising number of sites are using WebSockets, including multiplayer games.

Early Hints and the speculative connection improvements are also nice to have, as they should keep Firefox page loading performance competitive as more and more sites support them.

DNS over Oblivious HTTP is also a pretty important privacy improvement for DoH, so it's great to see that it has a negligible performance impact and we can move ahead with it.

There was also a captive portal fix, and some of the new contributors helped out with interop2023 fixes, which is very cool to see.

And the planning for off-main-thread networking is very likely to lead to performance wins down the line, if not also security wins, so it's worth keeping an eye on as well.
