The final push to start using Firefox over Chrome on Android might finally be thanks to the enormous selection of add-ons (Firefox’s version of extensions) coming out next month. Chrome doesn’t offer native support for extensions in its mobile app. Also, better security.
Try AniWatch for example and slowly scroll across the episode list.
Confirmed laggy for me running Fennec on Android 13 on my S21.
I’ve encountered this laggy scrolling on other websites as well since switching to FF ~4 months ago.
I tried it. It appears to be an optimization issue. Firefox struggles a bit for some reason but not Chrome. Probably can be reported on the fenix repo for Firefox.
