I honestly have no idea of the root cause. Different users are reporting different things. It seems to manifest differently for everyone. At a high level I would say it's due to the use of a JavaScript framework as a purely static HTML/CSS only site should not be doing this.

What refresh rate is your display running?
Very strange! Everyone who has replied has had a different experience on this website. It's probably an issue with the website, not Firefox per se. It simply manifests on Firefox for me personally.
Yeah it's incredibly annoying. I can't remember the exact details but a while ago they removed about:config from the stable build and I was using a setting in there. Okay well I can just use the beta build right? Except the beta build took away another different feature that the stable build had!
Yeah I understand. For something you use so actively you want it to be as seamless as possible. Maybe have another look at the "install to home screen" option though! I think you can do it on Chrome too btw. But I believe it should actually open as a seperate "app" on your phone.
So instead of having 1 browser app that contains whatever you're browsing + your dashboard, you could have 1 app for browsing + 1 "app" for your dashboard. It would allow you to even close down your browsing while always having an open dashboard. Maybe it doesn't fit your flow but it seems like an option worth considering if you haven't already.
it seems everyone has had completely different results! I've uploaded my experience here: video
for me if you look closely, ff hitches and lags on scroll while chrome scrolls perfectly smoothly
sorry I wasn't sure where to upload the video running a pixel 7 pro it's hard to come across on video but it is there. hitching/jittery/lag on ff, perfectly smooth on chrome
i'm surprised by the comments, everyone has been having mixed results
I think because of the JS framework it's using is causing performance issues. Ironic because the website claims 98/100 performance score - the highest of all those that they tested. It works perfectly smoothly on Chrome for me. A simple page like that should not lag/hitch at all.
Ah I see what you mean. Yeah I even had a quick look at the beta version where you are able to access the about:config and I couldn't find an obvious config setting for this either. Firefox on mobile definitely isn't perfect and especially if you have a specific use case. Just a suggestion that may be an alternative for you: if you press settings then add to home screen, does that hone screen shortcut work for you?
Massive lag on scrolling. Are you not seeing this? I'll record the screen in a minute.
Random performance issues
Menu doesn't open in landscape mode
Tab overview page not working consistently - this one is hard to capture right now but what happens is when you have a large amount of tabs open (say over 30), when you hit the tab overview button it doesn't take you to the currently open tab in the list, instead it takes you to the very top. This is not the normal behaviour. If you open and close it a few times it will randomly work properly 1/10 times.
