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.

Some Firefox users noticed playback issues on YouTube for several months. These affected high resolution videos only, from 1080p and up. To make matters worse, no clear pattern could be identified.

Some videos played fine, others would stop abruptly when they ran out of buffer.

I solved a lot of performance issues I had with yt playback by disabling Ambient Mode (it's hidden under cog menu in the player). No clue why, but it was causing massve CPU usage.

Yeah. I hate ambient mode. Kills battery life on all systems.

It's also really ugly and distracting.

I'm not sure why, but ambient mode also introduces a lot of color banding for me. I find it odd because it doesn't occur in similar dark-gradient scenes while gaming, just YouTube.

My guess is that it's supposed to look good if you have HDR enabled (which gives you 10 bits per color channel, although even with HDR, the desktop UI still renders in 8 bits per channel).

But still, it looks terrible for most people, and is a complete waste of resources. Because of the horrible banding, I initially thought something was wrong with my monitor. I don't understand why they added this feature.
