Greasy Fork

I can't seem to see any download buttons. All I see is the "show/hide" links button, which opening just shows me a small drop down with the words "Stream Video ID: Adaptive" and a link underneath all of that to an online video and audio merger.
I am using Tampermonkey on Google Chrome. I tried disabling every other extension, and this is the only script Tampermonkey is running, so that can't be it. I checked several other videos so I know its not just the one video that's causing issues.

I don't know. It works for me and I can't fix issues that I don't have. You could try login/logout your google account.

same thing here. kinda bad

It works for me:

well that's crazy but for now it dosent work for others
this is what bugs according to the console

Try Violentmonkey. Had same issue on Firefox with Greasemonkey.

Greasemonkey is not compatible with other userscript manager. This script doesn't support it at all.

Stopped working here. I am attaching the relevant part of the console.

I CAN'T fix problems that I don't have, so this can't be fixed until I encounter it.

bad dev, we literally giving the full error log and "nah i dont have i cant fix" you know other devs face issues they dont have too and still attemp fixing.
Will leave a downvote for now

Becuase that error log isn't enough. What I need is a enviroment where error happens, but I don't have.

Now it works.
It seems that youtube is making some test changes in random pages (maybe on selected datacenters) and the script that depends on it do not work. I had some similar issues with my (commercial) project.

Nope, doesn't work. While I agree that it looks like YT makes and/or made changes and sometimes (on some videos) it worked yesterday but today it didn't work on a single video. I tried Tampermonkey and Violentmonkey, just to make sure. I even downloaded a fresh copy of Firefox portable with just Tampermonkey and this Scrip installed.

@ Maple
Can we help somehow? I mean I could provide you with a pre-configured copy of Firefox 82.0 portable if you want.

Same issue happened to me today..

New version is just published, maybe it will fix the problem

10/27 Just tested. Unfortunately the problem still exists. :/
10/28 Today all videos I tested work again. Thanks.
