YouTube Center is the best browser extension running on YouTube that I have seen. I can not share.
Actually, this extension solves, if not all, most of the problems that we encounter on YouTube and which have been recalled more than once in Habré. The expansion itself was also
talked about on this site, but how good and convenient it is, which deserves a separate post.
YouTube Center features
Addition allows:
- place the video in the center of the page ( 1 )
- specify player size ( 2 )
- specify video quality ( 3 )
- disable autoplay and video buffering, including in Linux in HTML5 ( 4 )
- disable Dynamic Adaptive Streaming over HTTP (Dash), which does not allow to move freely along the video, because buffering starts anew each time ( 5 )
- disable ads, including ads inside the video ( 6 )
(numbers in brackets indicate links to comments on Habré, which talk about the desirability of such features on YouTube)
There are other small buns, like the possibility:
- download videos (with the choice of quality, format and video title)
- delete video offer at the end of viewing
- specify the type of player (Flash or HTML5)
- specify the resolution in which the clips are loaded
- add auto light, choose its color and transparency
… and much more
')
As a result, get something like this (clickable):

However, all the functions are perfectly configured, and your version may be completely different from this one. The main thing is a choice, and how to use it - you decide.
The YouTube Center extension is cross-platform. It works under Windows and Linux (verified), download statistics indicate that it is installed on both Mac OS and Android.
There are versions for Firefox, Chrome, Opera (including Opera <15>), Safari, Internet Explorer, Maxthon
Extension home page:
userscripts.org/scripts/show/114002After installing the extension on the YouTube page in the upper right corner appears the settings icon. The settings panel conveniently opens on top of the existing YouTube page and allows you to customize a lot of different parameters.
Installing YouTube Center
A few words about installing YouTube Center.
For Firefox and Opera, everything is quite simple, YouTube Center is on the add-ons page, where it is easy to find and where it is convenient to install.
Firefox: addons.mozilla.org/ru/firefox/addon/youtube-centerOpera: addons.opera.com/en/extensions/details/youtube-center/?display=enGoogle chromeIn Chrome's online store, this extension has not been approved.
To install this extension in Chrome, you will have to download it to your computer from the extension’s home page via the link
Chrome addon .
Then open the Chrome browser extensions page: chrome: // extensions / and drag the file with the extension to this page.

What is interesting, despite the fact that YouTube Center was not approved in the Chrome online store (why, by the way? No versions?), There appeared an extension of the same name by another developer, rather clumsy and incomprehensible. It is assumed that it optimizes video for widescreen monitors. In fact, it shifts the player to the side, closely pressing it to the left side of the screen, does not change the size of the player, does not add settings, does not create any new functionality, and does not block ads.
Where did this extension come from, which is called exactly the same as the existing one - it is not clear.
Internet ExplorerThe most difficult, as always, installation of the extension for Internet Explorer. It is so complicated that it offers a separate, rather big
tutorial .
I'll try to cut it a little.
First install the free add-on for Internet Explorer - IEPro
Unfortunately, the support for this add-on has been discontinued, it is not on the official website. Download IEPro at
this link .
During the installation process, you are prompted to install ProgSense. We refuse.
After installing IEPro, go to the folder C: \ Program Files \ IEPro \ userscripts (for 64-bit systems C: \ Program Files (x86) \ IEPro \ userscripts) and delete all the files that are there
For IE 11, download
YouTube Center 2.0 ;
for IE 10 and below -
YouTube Center 1.32.4 and place them in the userscripts folder that we just released.
To do this, click on the link with the right mouse button, select "Save object as ..." in the context menu, specify the path to the userscripts folder and rename the 622431.user.js file to YouTubeCenter.ieuser.js.
Go to the settings.
In Internet Explorer 11, you need to disable the extended protected mode (
how to do it. Instruction ).
Disable Grab Pro.
Tools - Browser properties - Programs - Add-ons management - disable Grab Pro and IE7Pro Grab and Drag, leave IE7Pro BHO and IE7Pro Preferences enabled.
Rebooting the browser. The IEPro icon appears on the command line. Click on this icon, go to the settings of IEPro. In the “Options” section, we tick the “Scripts and Add-ons” line, in the “Scripts” section, check the “Allow custom scripts” and “YouTube Center” checkboxes:

The quest was still there, but if everything was done correctly, a gear will appear on the YouTube page - the YouTube Center extension settings icon.
Summing up
What are the advantages of such a complex expansion from my point of view?
To implement all the features it offers (video quality selection, player size increase, auto start disable, advanced video settings, the ability to download videos, etc.) in Chrome you need to install a whole bunch of other addons:
Running video in HD quality:
Auto HD For YouTube
chrome.google.com/webstore/detail/auto-hd-for-youtube/koiaokdomkpjdgniimnkhgbilbjgpeakIncrease player size:
Youtube Resize
chrome.google.com/webstore/detail/youtube-resize/jjeehmofdedjmnfainleedcifafige/relatedDisable video autorun
Stop Autoplay For Youtube
chrome.google.com/webstore/detail/stop-autoplay-for-youtube/nilnpbhnhmmjioijfgilcohbknkgfmpa(you can disable autorun in browser settings)
Download video
YouTube Video Download
userscripts.org/scripts/show/62634Block ads
Adblock copes with this, which is needed on other sites too, so that it can be not considered
Darken the contents of the page around the player:
Turn Off the Lights
chrome.google.com/webstore/detail/turn-off-the-lights/bfbmjmiodbnnpllbbbfblcplfjjepjdn?hl=enEdit video settings
YouTube Options
chrome.google.com/webstore/detail/bdokagampppgbnjfdlkfpphniapiiifn?hl=enTotal we get six extensions, instead of one.
But even if you install them all, the result will not be as user-friendly as a single well-thought-out extension.
There are YouTube Center and disadvantages.
It is not always possible to download video as 1080, although such a resolution is specified for it, the music is downloaded in a format that involves converting it.
Video viewing is not implemented at all in countries where it is prohibited for viewing.
To view this video, you can use the
YouTube Unblock site or the ProxTube extension for Google Chrome, Firefox
proxtube.com/install.php , which automatically processes and allows you to view all inaccessible video.
But generally speaking, YouTube Center makes using the site more convenient and comfortable than it was intended by developers.
It would be just great for all popular sites to create such extensions. It would be even better if the functionality provided by the extension was implemented by the site developers themselves, but this is already from the realm of fantasy.
