Unfortunately didn't work. Rated 1 out of 5 stars

Running Firefox 52.3.0 (32-bit) in Windows.
Went into Addons, about:addons. Confirmed Youtube-No-Buffer was activated.
Went to www.youtube.com. Clicked on first video. It cached as per normal even after clicking paused.

I would just like to be able to reply to comments without raping my data.

Stopped Working! :( Rated 3 out of 5 stars

I would normally give this extension a 5, but I'm getting tired of Firefox extensions to suddenly stop working by not pausing YouTube videos when loaded. My desktop computer is up to date with FF 55.0.3 and all extensions up to date. However, this extension stopped working today (Aug 29, 2017 at 3:30am). I fired up my laptop which I don't updated until I know the desktop will me happy and this extension is just all of a sudden not working on that computer either! There was recently another addon by another author that stopped working all of a sudden. He was flooded with people complaining about this. It was found out he wrote self-destruct code into the addon to quit at a certain date/time. After all of the complaints, within 24 hours he had an update in which the extension just magically started working again. Is this the case here also?

Works fantastic with current Firefox. Rated 5 out of 5 stars

Automatically prevents autoplay when you click a link to a video. Excellent. Now videos don't play until I click the play button.

Feature removal. Rated 1 out of 5 stars

Version 0.1.6
"3. YouTube No Buffer does not prevent playlists from auto buffering once playlist starts to playing."

Removed the only reason I used the extension with no option to turn it back on. Reverting back to an older version works, but why could you not just add an option to turn this on or off?

Simple, effective, no setup needed, saves your mobile data allowance Rated 5 out of 5 stars

I use this YouTube No Buffer add-on with my laptop as it prevents YT videos from downloading that I may not want to watch, this add-on saves heaps of my mobile data allowance. This add-on does exactly what it says nothing more nothing less, there is nothing to setup.
For those people unsure if they need this app, please note when you have prevented YouTube from automatically playing it doesn't necceassarily mean it's not auto loading (buffering), if you notice the grey bar loading accross the bottom of the video that's chewing up your mobile data, this app prevents that from happening.
BTW A couple of people have left reviews stating that this app used to work and now it doesn't, this may not the developers fault. Youtube regularly changes the way videos play/upload etc therefore the app may need to be updated. If this happens to you contact the developer and let them know as they may already be attending to the add-on issue or unaware there is an issue. It seems unfair of people to give this add-on a poor review when it users state that it used to work well then give it 1 star review when YouTube changes the way the video works without the developer having a chance to update the add-on. I highly recommend this app for people wanting to reduce their mobile data.
