Laggy Facebook (Safari)

The more you scroll the more memory is consumed. This happens with sites other than Facebook. One will think something like this is a memory leak with Safari as it doesn't happen with Chrome, Chrome's cousin Microsoft Edge nor Firefox. And if you leave Safari open it just keeps consuming memory until it closes or reloads the tab.

Another problem with safari is when scrolling it suddenly jumps through rather then smooth scrolling, its hard to explain but when scrolling down the page rather then smooth it suddenly jumps further down the page hope people know what I mean, try msn.com (this is not the only website that it does it on. Also someone said its a Facebook problem with laggy website it never used to be like this before update so to me why should Facebook or others adjust it to safari

I've seen some new Facebook problems on Safari since I updated to Big Sur. Facebook Live videos not working. I've switched to Chrome only for Facebook. I'm also having problems with some other programs since the Big Sur update. Hopefully the interface will smooth out soon.

Same issue here with a new MacBook Air with the M1 chip. Everything is updated - nothing pending at the time of this post.

Seems like SAFARI is the problem. Going into the activity monitor will show Safari hugging lots of memory (in the gigabytes...) while Facebook is running. This cannot be reproduced when using Chrome in the same website.

The sad thing is that Chrome works in the same computer, and the same FB account without lag - super smooth. It's a shame reading all comments and apple not addressing this. Again...Chrome seems to be OK.

Hi,

The same problem. It started when I got the newest update Safari for my MacBook Pro 15 2019 i9. I also have MBP LATE 2013 with Mojave without the newest Safari and it works perfectly. I'm really angry I spent a lot of money for MacBook and SW and it absolutely not working!

TO Apple. Please RELEASE UPDATE and FIX IT or Call to Facebook to fix it!!!! Or Do you want to use FIREFOX where it works great?

It has been 6 months and no release any fix or update! I have already tried to reinstall a new system=THE SAME!!!!

It' not only Facebook that's choppy in Safari now. It has been my number one browser since 2003, but now I have to say that I'm forced to use Chrome more and more because Safari is so choppy on sites like Facebook.

The main reason I have to switch browser is that I'm working as a Salesforce Developer, and using their new Lightning-interface is extremely choppy and behaves strange in Safari.

Performes well on Firefox, Chrome, and even the latest MS Edge with their new engine on macOS.....

I would love to have just one browser, just like I've had in the past, because I love the integration and device sharing features of Safari.

I agree. am operating a MacBook Air that's only couple of years old and OS BigSur, but since new FB format etc. this has definitely been more of an issue. Is this because FB won't 'play' nicely with Apple & vice versa?

It's certainly not anything we users can do anything to correct. It's obviously a FB/Safari issue, and I find it hard to believe, after months of this BS, that Apple's brilliant programmers/engineers can't figure out how to make Safari handle Facebook! Every other browser does it, just not Safari. This is ridiculous....

yes it's true, i've just bought the new macbook pro 13-inch m1 chip and using the safari to browse Facebook and it s super laggy, even after around 10 minutes, it appears a note says This webpage is using significant memory. Closing it may improve the responsiveness of your Mac.

how disappointed about Safari

after about 3min of looking a Facebook on Safari it really starts to lag to the point its not worth looking at and get a message at the top that says "This webpage site is using significant memory. Closing it may improve the responsiveness of your Mac." and then realize I have wasted 3min on Facebook.

I'm having an issue as well with Facebook on Safari. I'm using a 2020 iMac and just upgrade to Big Sur hoping that would fix it. Still super choppy. This is unacceptable on brand new machines.

This is now the Safari experience on Facebook ...

Rummage around with the Facebook support website, and see if they’re aware of this?

I have an IPad pro

dont bother I am getting the same problem on Catalina but only with safari if I use Chrome there no problem at all.
