How do I block Youtube's suggested videos?

I find myself wasting far too much time watching Youtube videos. I start by watching a legitimate video, and then click on one of the suggested videos, and keep on going for hours.

Is there a way to block the suggested videos in Firefox or Chrome or Opera?

Specifically, I want to block:

• The videos thumbnails displayed in the side bar on the right
• The videos thumbnails shown at the end of playing a video
• Optionally, links to other Youtube videos in the video itself, that the author has inserted.

I would prefer not to block ads, although this is not a requirement.

This can be achieved by using Adblock Plus on Firefox or Chrome. First install Adblock Plus. Then go into Adblock Plus' options (Filter preferences on Firefox) and create a custom filter. Then copy each of these lines separately into the filter list:

/yts/swfbin/player-*/endscreen.swf
youtube.com##div.videowall-endscreen
youtube.com##div.watch-sidebar
youtube.com##watch-related

This will block the video thumbnails shown in the sidebar and at the end of the video. It should work for both the html5 and flash youtube players in Firefox. In Chrome to get this to work properly I needed to enable the html5 youtube player. Visit https://www.youtube.com/html5 to opt into using the html5 player.

To block the links inside videos (annotations) go to your youtube settings page. Then go to the playback tab and disable the check box that says "Show annotations on videos".

If you don't want to block ads, just disable all the ad lists in Adblock Plus.

DF YouTube (Distraction Free)

It's browser extension, recommended by Center for Humane Technology. It lets you block suggested videos, and also if you want, the feed, subscriptions and comments.

• Download for Chrome
• Download for Firefox

With uBlock Origin (Chrome version / Firefox version), AdBlock, AdBlock Plus, or any browser extension that can use AdBlock Plus syntax filter lists, add this filter into your custom filters (called My filters in uBlock Origin):

youtube.com###related

That will block the 'Up Next' video and the list of related videos shown at the right sidebar.

The YouTube Annoyances filter lists (also for uBlock Origin, ABP, and similar extensions) might also be of interest. It aims to block many YouTube annoyances. It has a 'Block suggestions' list that will block suggested, recommended, or featured videos in the end screen. It can also block recommended channels on the homepage and related/featured/popular channels on channel pages.

Try StayFocused add-on for chrome. It can be found here: https://chrome.google.com/webstore/detail/stayfocusd/laankejkbhbdhmipfmgcngdelahlfoji/related What this add-on does is limits the amount of time you can spend on a website in it's list. As a default, sites like youtube.com are "blocked", so that you can only spend a maximum time on them. You CAN increase this time if you want, however, there are mechanisms in the add-on such as positive reinforcement to help you stop procrastinating.

I would suggest trying out the YouTube Center greasemonkey script (also comes in the form of an independent add-on/extension). It is available for Firefox, Chrome, Safari, IE, and a bunch of others. You'll want to get the latest developer version though, as the current official version is very out-of-date and is broken in many ways.

It has options for disabling the endscreen on videos

You can also hide the recommended channels column

To block links to other videos within the current video you are watching, you can disable annotations by default
