Works better when this is toggled off in about:config maybe.

it seriously is getting to a point where i'm going to have to either quit using firefox or quit using youtube. i only get massive memory leaks and CPU usage when as few as one youtube tab is open

It functions like shit on all browsers, it progressively eat up memory the longer you have a tab open.

Here are some workarounds:

- Enable Hardware Acceleration: In Firefox settings, ensure hardware acceleration is turned on. This can improve video playback significantly.

- Use Extensions: Add-ons like “Enhancer for YouTube” allow users to force higher video quality or tweak playback settings.

- Try User Agent Spoofing: Extensions like “User-Agent Switcher” can trick YouTube into treating Firefox like Chrome.

- Keep Firefox Updated: Mozilla regularly improves codec support and performance tuning.

If you’re a Firefox loyalist, these tweaks can help bridge the gap. But if seamless YouTube playback is a priority, Chrome might still have the edge—at least for now. Want help optimizing your Firefox setup for YouTube? I can walk you through it.

Every website performs worse on Firefox than on Chrome.

YouTube's anti-adblock garbage fucks it up hard, especially on Firefox where it's mo longer being updated.

Works the same for me in both browsers.
Try these:
media.av1.enabled
dom.media.webcodecs.h265.enabled

stop using web browsers for youtube

It's been working pretty bad for me on MS edge as well. It's like they sabotage the site if you use it with UBO enabled. Works fine with adblocker disabled though

>Try User Agent Spoofing
I like this one, but I think this doesn't work anymore + it makes many websites think you are a bot. I think google services can exclusively talk to google chrome with an unique identifier, because even other chromium based browsers are worse on youtube now.

because Firefox is slower than Chrome. it's an unavoidable fact.
That's why I still keep at least one Chromium browser installed.

i am tech illiterate. what does this do?

>>107077657
yep, they're doing it on purpose. they used to show the "experiencing interruptions" shit on and off but once youtube changed their UI (which is terrible now) it's a permanent thing on every video for firefox users

>>107079613
Don't do this. It makes mustard gas.

freetube is electron web browser
not a problem with my youtube client

>>107073257
After it broke the ability to view videos in an isolated /embed/ tab I started using youtube-local. It uses a different player so it might have better performance for you, I don't know. I also expect it to probably start getting hit with functionality-breaking updates because youtube somehow gives a shit about the 0.005% of people who don't watch their adriddled garbage.

Anyway, personally I didn't have issues with playback unless I was watching a livestream or if I was jumping around a lot at high (1080+) resolutions.

All google services work worse, not just youtube.
Try maps with the 3D globe view, it stutters and lags on Firefox compared to Chromium based browsers.

There's dozens of reasons and basically none of them matter. To setup firefox you need to be debloating it with a user.js file, Have minimal extensions, and then be running it on a decent CPU. My core 2 laptop runs firefox like shit no matter what I do, my 10900k I can't even see the difference between the latest chromium build and FF they're identical and I've never had this kind of a memory leak before >>107073914


If you can't manage to get FF to work for you on your hardware just use ungoogled chromium. Your PC is either too shit or you don't have a clue what you're doing I guess, I don't really know what to tell you, firefox is ultimately a bloated cobbled together piece of shit with major feature creep adding to the bloat, it's only going to get worse here as time goes on so if it's bad for you now, it's gonna be really bad in a couple more years.
