In my experience I can't stream video on firefox without the video freezing within the first 5 minutes, and it feels clunky even with non video webpages. I really hate google the company, and I'd love to stop using their software, but so far I have yet to see a browser that even comes close to chrome.

What OS, hardware and video platform(s)? I haven't had any issues with Desktop Firefox on Windows 10 on any of my Core i7 machines, when watching YouTube/Vimeo. Even my old dual-core budget Inspiron 3137 laptop works for YouTube and Firefox as well as Pandora/Firefox/bluetooth audio blasting.

(It does like to consume RAM as if it was running SQL Server though.)

It happens both on my Mac Book Pro and my Windows 10 desktop. I don't have the problem as much with pre uploaded videos but with live streaming sites like twitch.

Also having a good time with Firefox on macOS running on an early 2018 MacBook Pro. It has fully replaced my Chrome use at work.

Same here on Arch Linux for me.

I am able to stream video on Firefox on Windows, Linux, and Mac, including on a computer with a 2nd-gen i3 with 4GB RAM. I suspect there may be something besides Firefox at fault for your issue.

I've been using Brave, which is basically Chrome but even faster, and with more privacy features. All Chrome extensions work.

The only problems I have with video in Firefox on Mac are with Hangouts / Meet sometimes not working correctly. This is likely due to Google not cross browser testing.

This, very noticeable with something like shadertoy.
