You can look at these prefs in about:config to see what settings work for you to block media auto-play.

• media.autoplay.default = 5 [0:allow;1:blockAudible;5:blockAll]
• media.autoplay.blocking_policy = 2
• media.autoplay.allow-extension-background-pages => false
• media.autoplay.block-event.enabled => true
• media.block-autoplay-until-in-foreground

You can open about:config via the address/location bar. You can read the warning and click "Accept the Risk and Continue".

to be frank it's not that I don't appreciate this, and it is what I had originally been looking for (and shortly after posting this, I realized that it was just the website made it look as if the videos would still autoplay with autoplay disabled,), but what I was asking here was to disable all video playback, and changing those settings does not disable all video playback.

I get the intent of your answer (I do appreciate it), but it makes searching for questions and answers more difficult. If there is not a way to disable video playback I would rather delete this thread/topic if possible; I don't want someone who is trying to find a way to disable video playback to have to check this topic to find no answer to their question

edit: if there is not a way to disable video playback and if there is no way to delete the topic, I'm just going to reword the original title/post to be about disabling autoplay

If there or if there is not a way to disable all video playback on Firefox please let me know. Otherwise if the question does not receive an answer I would like to request that this topic be deleted.

I do not want someone to be searching for the answer to the question and end up wasting time by checking this topic when there is not an answer.

This isn't urgent at all but I just want to be clear that if no one answers the question I am requesting that the topic be deleted.

You can search the Add-ons website for an extension that can block videos and other possible JavaScript animations, but there can always be cases that slip through.
