YouTube 2 Player Firefox

YouTube 2 Player

Watch YouTube videos in an external player.

Features & Capabilities

Legacy version For pre-Quantum Firefox or Pale Moon, the legacy version can be found here: https://github.com/sumzary/yt2p/releases/tag/v2.1.1

Setting up After FF57, an additional Native Client is required. Download yt2p-nativeapp.zip and follow instructions here: https://github.com/sumzary/yt2p/releases/latest

Configuring players Open the add-on settings. Players are sorted into groups. Pick the active group on the left itembox, then the active player on the right itembox. Below the boxes are the Name, Icon, and Command input fields for the active item. Command is the most important, requiring the player executable path and URL identifier.

"C:/Program Files (x86)/mpv/mpv.exe" VIDEOURL Opens a video in mpv player. Notice the quotes around the file path.

"C:/Program Files/youtube-dl.exe" -f 22 VIDOURL Downloads a 720p video. Change the exe path to the actual youtube-dl.exe file.

youtube-dl --format 140 --extract-audio --audio-format mp3 VIDEOID Downloads a mp3, "140" is a audio-only format on YouTube, more info here: https://github.com/rg3/youtube-dl/blob/master/README.md

LINKURL - becomes the raw right-clicked link url, VIDEOURL - is the same, but standardized, if it's a YouTube video url. VIDEOID - is the extracted video ID.

Why bother? It'll probably run smoother, you can make use of the player's filters, change the aspect ratio, maybe save the video for later... it's just what a professional ought to do.

mpv The best player I've found. https://mpv.io/

youtube-dl Download videos in any format you'd like, including audio-only. https://rg3.github.io/youtube-dl/

Media Player Classic BE A light-weight player based on the original MPC and the MPC-HC projects. https://sourceforge.net/projects/mpcbe/

DAUM Potplayer https://potplayer.daum.net/

VLC Media Player http://www.videolan.org/vlc/

BS Player http://bsplayer.com/

Notes This add-on is no longer under active development. If this add-on feels convoluted, it is. It's frustrating having to use the native messaging API for something as elementary as running an executable, a no-brainer before Quantum. Development shall continue once Mozilla has provided an alternative API. Thank you for your interest in YT2P.

Is YouTube 2 Player Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

YouTube 2 Player requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

YouTube 2 Player is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
