Hi everyone, This isn't the biggest issue, but it's a bit concerning, and I'm hoping someone knows a solution.
I have my autoplay settings to block audio and video, with just the default exceptions. However, certain sites, such as https://youtubetranscript.com/ will autoplay videos anyway. (Try pasting a URL of a YouTube video in there and search, and the results will immediately start playing, which is aggravating and has actually disturbed people before when I forget that's a thing that happens.)
I've done some searching, and checked about:config, but I think everything is okay in there.
I've also tested this in LibreWolf, where the exact same thing happened.
I also attempted to test it in Tor, but for some reason I am unable to connect to the Tor network right now.
I'm hoping I can find the root of the problem since clearly if it happens on this site, then it's likely to happen on others, and I'd rather not have videos autoplaying when I expect them not to.
This may or may not happen in other browsers, but it's still a Firefox issue, since Firefox presents us with a setting to disable autoplay, and one would expect it to work.
