To save a search: "Ambient mode uses a lighting effect to make watching videos in Dark theme more immersive, by casting gentle colors from the video, into your screen's background."

Neat idea, I bet the intern had fun implementing it, why was it on by default?

Looks like it's a Youtube feature rather than a Firefox feature?

They are not the intern anymore - they are senior vice president of battery draining, this feature absolutely killed it at the end of year review.

If you're on a Mac and using FF (probably not FF specific), turning off "ambient mode" in youtube can save 30% cpu. I just found this out while searching why FF was taking 90% of my cpu while watching youtube videos in normal mode, but went down to 40% use if viewing in full screen. Turns out that this youtube "ambient mode" was the culprit. My lap is now cooler and the fan doesn't turn on anymore. I wonder how much…

I honestly thought my monitor or GPU was having issues with weird colour banding around YouTube videos. Turns out it was an intentional choice they made to do that. I don’t know why it’s on by default.

I just bought a Macbook because my dedicated Linux laptop, made by a popular Linux-only manufacturer, had so many issues that I got tired of diagnosing. I love Linux, but it's not a panacea for every computer issue under the sun, just a few of them. I, personally, am stoked I no longer have to deal with issues with this new machine, and can just take it into a Genius bar appointment to let someone else deal with it,…

You are not sellout but just the average Joe. No problem with that I guess. Have fun with your Mac that uses a soldered ssd that when failing makes your whole Mac useless as well.

Meh hasn’t happened yet but I’d just buy a new one. That being said, I always also have a windows and Linux machine, they’re just not my daily drivers.

> Are you sure you want to invoke this logic? Because following it through imagine the energy savings if Firefox users switched to Chrome. Ironically, Mac users routinely complain about how power-hungry Chrome is on the Mac. Safari is significantly more efficient.

Is that because of the quality of Chrome or because Safari is a "blessed" application and probably gets to do things other applications do not? Entirely serious question. Apple is known to severely privilege their own applications over competitors.

Blessed or not, I still end up using Safari. The improvement in battery life is too significant to ignore

> I, personally, am stoked I no longer have to deal with issues with this new machine, and can just take it into a Genius bar appointment to let someone else deal with it, for pennies a day. You can't get that on Linux! Honest question. If you could get that on Linux, would you? and what kind of pricing would you consider reasonable? Is it something that would have to come with the computer (i.e. would you pay for it…

I would pay the same amount for a Linux laptop that worked as easily as a MBP and had similar build quality, performance and battery life.

Howver, whatever crazy-stable and easy to use and well supported hypothetical Linux this is wouldn’t be compatible with my “real” Linux use cases so I would then also install Arch or whatever and live with constantly borked everything and just swap between my Arch “Dev” OS and my “Linux Mac” business/work/consumer OS.

Current Linux cannot be made “MacOS”-stable. But maybe in 5 years.

That's because optimizing for battery life is a stated goal of the Safari team, it's actively benchmarked

Because the target audience for the feature is not tech savvy people but common users whom won't know it exists until it is shown to them/might be intimidated to delve onto FF settings If you are tech savvy, you are then expected to be able to "bear the burden" of turning the feature off if it bothers you

> might be intimidated to delve onto FF settings

It’s a YouTube setting, not a Firefox setting.

To save another search: On desktop and mobile devices: While playing a video, select the Settings button. Locate the Ambient Mode setting in the list of preferences. Toggle it to off to disable Ambient Mode for all videos on YouTube (in that browser). It's in the same popup used for video quality and playback speed.

I dont have that option. firefox on windows 10.
