Not working in Firefox

Doesn't work for Rumble

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.

This extension is the source of many errors when logged on to cloud.google.com

Several extensions were disabled in Firefox while trying to track down the origin of the

"Oops! An unexpected problem occurred. Please refresh your browser."

messages when logged into cloud.oracle.com

Firefox 95.0.2 64 bit, the current latest version, on Windows 10.

This consistently occurs when choosing items from the menu at cloud.oracle.com

After disabling "Disable HTML5 Autoplay", the errors stopped.

Checking the Firefox Console, the error was always this url:

view-source:moz-extension://86436a12-f1b7-4665-ba83-101479f2641a/js/content_script.js

and this bit of code:

function injectScript() {
const domain = window.location.hostname;
const scriptFile = domain === 'www.youtube.com' || domain === 'gaming.youtube.com' ? 'youtube' : 'inject';
const script = document.createElement('script');
script.src = browser.extension.getURL(`js/${scriptFile}.js`);
document.documentElement.appendChild(script);
}

This code may be here due to numerous complaints about compatibility with youtube.

In any case, I have removed the extension, and the problems went away.

перестало работать

OK On Many Sites.... but it also breaks image uploads on Google Group sites.

Since the late 70s and well into the 80s currently version 88 of Firefox I had a problem with most videos displaying the following message:
"This video This video cannot be played because of a technical error.(Error Code: 200001)"

I have no proxy set and all drivers are current.
Researching I found many having same or similar problems but nobody having a solution.
That was until I came across a locked and archived forum thread: https://www.reddit.com/r/techsupport/comments/aday21/video_error/

The last reply, by "SlickStretch" was the correct answer and solution.

"solved by disabling the extension: 'Disable HTML5 Autoplay.' Try disabling/removing this extension or any similar ones."

This used to work fine, but in the last few days it has started BLOCKING videos in Facebook and newspaper sites. Have to disable it in these sites if I want to see videos, but then they autoplay, which is precisely why I NEED the extension! The extension is now almost useless.

Doesn't work any longer on Youtube.

Don't work on morgenpost.de
funktioniert nicht auf morgenpost.de

It did not disable autoplay on Tubi. Nothing else has stopped autoplay on Tubi without breaking manual playback.

Does not disable autoplay, nor preloading.

Addon not bad, but would like to exclude some domains. Unfortunately it does not work. Must switch it off manually, if needed. It sucks.

You had ONE JOB...

It doesn't bloody work!

BREAKS VIDEO on some sites .. espesially IMDB
I dont advise anyone to install this addon unless it gets a major update

Diese App blockiert unter Firefox in GMAIL beim Schreiben von Mails das Drop-down-Menü der vorhandenen Kontakte/Gruppen. Man kann Kontakte nur mehr einzeln, händisch eintippen. Aus diesen Gründen ist das Add-on unbrauchbar.

Works but errors videos... try 'Video Autoplay Blocker' addon. It works good in my testing so far.

It puts a 'Play Video' in top corner.. WORKS GREAT and I checked the code with 'Extension Source Viewer' and it is clean, no spyware in it. 5 STARS!
