I never run into websites that don't work properly in Firefox that isn't a consequence of one of my addons. Do you encounter them commonly?

View on HN

For me Twitch, Netflix, a bunch of my banking websites and random others all have issues in Firefox. For twitch and Netflix it’s massive cpu spikes and battery loss, for the others typically just a complete failure to load properly.

sounds like video decoding in firefox. at least it's something under firefox's purview to fix if that's the case.

On a Mac or Windows (or Linux)? I find Firefox Mac a lot less pleasant to use than Firefox on Windows.

My experience is the same - I'm mostly Max/Linux and have issues on both but the times I have used FF Windows it has actually seemed decent on battery etc

Are you running uBlock Origin? As when a site fails to load properly for me it's usually requires loading stuff I have blocked, unblocking it fixes the issue.

I have had that happen (being the fault of the blocker) but for these it’s problems I’ve had even with blockers disabled

Indeed and almost always for that reason. It's more the performance that hurts me, perhaps my 'many tabs' style is better handled with the chromium process model.

I have Firefox containers and Simple Tab Groups extension installed, which keeps my tabs in the browser, but automatically suspends them when they are not visible. This was my sweet spot for tabs, because I do not have to bookmark them permanently, and I can instantly switch to my "workspace" anytime.

I experience the opposite of you with Chrome struggling with several tabs.

At around 30 tabs, Chrome absolutely throttles my moderately powerful 8 core 16 thread CPU laptop with 24GB RAM, while Firefox has no issues with it. Firefox doesn't even sweat even if I have those tabs open with Spotify and Gmail, one that presumably uses hardware DRM decryption, and the other websockets for email and chat, plus whatever tracking Google wants to do.

A friend of mine has over 3,000 open in a vanilla Firefox at this very moment. Firefox restores the tabs on each restart without loading them and suspends inactive tabs automatically.

I love FF but Youtube is a lag fast compared to chrome.

yea YT does suck a bit on FF, but there's some settings to try make it better - turn off the hover preview (https://support.google.com/youtube/thread/130441859/how-to-d...).

Also try switching to av1 codec, if you have a recent video card (https://arstechnica.com/gadgets/2022/03/firefox-will-efficie...), but not sure if it will help much if it's not the video lagging.

Curious if that's still the case if you disguised the User Agent as Chrome. I used to have to do that on FF mobile to make any of the Google products usable.

Probably depends on device people are using. I'm using FF on the M1 Macbook and it runs extremely fast but on a more limited device the difference may be noticeable.

I'm sure tiktok runs circles around Chrome on tiktok, too.

Just because it works doesn't mean it's snappy.

Does it really matter if it loads in 2 seconds in Chromium vs 3 seconds in Firefox?

When you're doing it hundreds of times a day, yes absolutely.
