It works... most of the time. I sometimes have to refresh the page to get it to kick in. But lately (April/May 2025) it has been interfering with some Captcha modules, especially Cloudflare. I can't get past the bot-blocker unless I disable this extension. This has happened only in the last 2 or 3 months, so I don't know if it gets caught in the captcha net in error or what. I don't know how to notify the developer directly so I'll have to put it here.

Rendbe hozza hogy a Facebook ne legyen az idegesítő automatikus videó lejátszás (amit mostanában tapasztalatok - hiába van ez blokkolva: ( 😶‍🌫️

Doesn't work at all. YouTube keeps autoplaying.

Great extension. Only drawbacks: it doesn't seem to have any effect on Reddit, and for some reason it prevents the Cloudflare Captcha to succeed on deepl's login page.

It did what it said and worked well for a few years. Unfortunately, it now somehow breaks Cloudflare verification, which left me unable to log into many web sites.

Causes problems with Google Recaptha v3

Doesn't work for YouTube videos on Firefox on my PC.
I recommend adding a section to the description that lists some of the most popular sites which it is known to work on [Facebook, Twitter/X, YouTube, etc]. And a list of some that don't.
Or if it only works on Firefox for Android then mention that. Something simple.

I've used it for years without problem, but recently I have been unable to complete "verify you are human" challenges on Cloudflare-protected sites, I kept getting stuck in an infinite verification loop.
After disabling/enabling all my extensions one by one, I figured out this the problem is caused by this add-on. I'm hoping that problem can be fixed by the developer, than I will happily go back to using it again and give a better rating.

Good extension, but unfortunately doesn'twork on mobile devices

Esta extensión funciona deteniendo la reproducción automática de los vídeos, pero consigue, por ejemplo, que Spotify no reproduzca las canciones seguidas, sino que se para cuando reproduce una, entonces hay que volver a clicar en continuar para que pase a la siguiente canción. Un desastre. La he tenido que desinstalar al instante.

(This extension works by detaining the automatic playback of the videos, but achieves, for example, that Spotify does not reproduce the songs in a row, but stops when one reproduces one, then you have to click again to continue so that it goes to the next song. A disaster I have had to uninstall instantly.)

Breaks *://www.zdf.de/live-tv.
With preference "Disable preloading" UNchecked it works fine.
This should be the default setting.

Does not working. Per-domain preferences can't be set too...

Blokování je fajn, ale správa stránek, kde má být povolen a kde ne, editovat nejde.
Bohužel způsobuje pád některých stránek, kde ani video není a blokuje ověřování "Are you human" např. od cloudfare.

Doesnt work on Yotube nor Facebook, i believe with the rest its the same.

Simply, but usefull!

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!
