Unfortunately, this extension causes issues with OnlyOffice integration with NextCloud. I have no idea why but it causes a Permission denied to access property "dispatchEvent" on cross-origin object. I cannot edit any documents with this enabled.

Needs option to prevent even loading the video without my okay (and the "okay" should be something difficult to accidentally trigger on the phone screen). Currently still allows sites to waste my data by pre-buffering a video I have no intention of watching.

In Ff 25.0.3 (64 bit) is working fine.Thankyou

it doesn't work for pixiv

Sadly, this add-on do not working good anymore. Needs update!

Not working in Firefox

Would be nice to have an editable white-list that allows regular expressions (or similar syntax). As an example, bandcamp has subdomains for each band and I'd like to disable it for the entire website, instead I have to disable autoplay for every new band I listen to.

Doesn't work for Rumble

Works perfectly on Rumble.

Does the job! I have used it for years now. 👍

Breaks CNN video playback. Built-in autoplay off feature is sufficient. Removed plugin.

This extension is no longer needed. Firefox already includes a setting to block media autoplay. Go to settings and search for "autoplay". Click on "Autoplay → Settings...". I suggest changing the default for all websites to "Block audio and video".

Firefox also makes it super easy to add exceptions for certain sites. Just click on the Permissions icon to the left of the address bar and it'll give you a quick drop down menu to permanently allow auto playing both audio and video or only audio.

Of course, although it is no longer necessary, I thank the author who kept this extension updated all the way until 2018. You helped a lot of us out,

This is a lifesaver. It blocks auto play on sites and that kills the drop down of vids on the same pages as you scroll. Also there are sites where auto play is preferred and this allows for exceptions.

Randomly Stops Working. Pretty Bad.

does not work on youtube autoplay and it wants permission on your website browsing.

I only have autoplay issues with one site. (Yahoo Finance) Firefox can block autoplay on initial load, but not when changing back and forth between tabs nor when scrolling up and down the page. After installing this add-on, it seems to help block autoplay when switching between tabs, but allowed autoplay when scrolling up and down the page. I believe Yahoo uses multiple triggers to force the videos to autoplay .. onHover, onFocus, etc. If it is updated to catch the other triggers, I will try it again.
