Thanks for the report, but I'm not able to reproduce the issue. For me scrolling is smooth and site navigation works fine.

Tested with: Browser / Version: Firefox Nightly 210427 (🦎 90.0a1-20210426094327) Operating System: Google Pixel 5 (Android 11) - 1080 x 2340 pixels, 19.5:9 ratio (~432 ppi density)

@hakkikaancaliskan could you try clearing cache/data/cookies, disable Ad-blocker (if available), or use a clean profile, and check again? Also if there are any changes made to default settings of the browser (e.g. in about:config) please revert to the default settings. You can attach the log and screen recorder and maybe record a performance profile and add them here.

@softvision-oana-arbuzov I've installed nightly from scratch. There is obvious stutters. Here is the video:

@softvision-oana-arbuzov and here is the perf profile https://share.firefox.dev/2PCcAti (This profile is taken with ublock but there is no difference with or without it)

Thanks @hakkikaancaliskan for the extra info.

@karlcow can you look over the perf profile?

Thanks a lot for the profile @hakkikaancaliskan

Ah that's interesting, because to my eyes and tolerance everything is fine. 🤣 I'm not the right person for this kind of details.

I have the feeling that the "stutter" are created by images loading delay. The network is very active. I have the feeling that @wisniewskit would be better than me at discovering any culprit.

Also the site is making all these requests which are not really cool for the browser.

On Chrome too. It's quite insane.

one request every ms.

I would be in favor that this site needs to be reached out. Could you do that @hakkikaancaliskan ?

There is no problem on safari(ipados) and Chrome(android). Maybe firefox can't handle fast enough that requests? I guess they don't care about firefox, if this is something with website i think we can close the issue 😔
