You can scroll to the next video fine, but if you continue to scroll to the next after that (3rd consecutive video) you get redirected to the first video you started with.

On the page of Youtube shorts make sure the video that was playing is paused before you scroll to next video as sometimes the previous one will keep playing and next one will not play.

You can take any random short, doesnt matter.

so ie. just go to: https://www.youtube.com/shorts/p0tXCbstr30

scroll to next short, then scroll again - then you will be redirected back to the original one.

No problems here with scrolling. If I scroll down using the mouse wheel then I get the next short playing and so on, it doesn't return to the top.

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

• switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
• do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

Ok wth, i did some testing around and turns out, this bug only happens for me, if im logged in. When i logout of YT, its working. Did turn off hardware acceleration, issues was still present. No idea whats going on. I did test this on an other computer, same result.

No problems here when I'm logged in to Google. Did you try top clear the Google cookies?

Ok this is not a FF releated problem. Did some more testing and it seems to be YT issue. My Account seems to be broken. I did test this again with different browser, logging into account and same issue! WTH lol. I then did create a new account, logged in, and its working again.
