How to install on Firefox Quantum?

[neilbalch]

Are there any plans to make this extension available on Firefox Quantum again? the Firefox Addons page won't let me install it.

Thanks,
Neil

Install Tampermonkey addon and use the Userscript: https://github.com/YePpHa/YouTubeCenter/raw/master/dist/YouTubeCenter.user.js

Make sure you switch to the old Youtube design before enabling the script, otherwise Youtube will be broken and you won't be able to access the menu to switch back to the old design.

I have a question : after switching the old YT design for installing YouTube Center with Quantum, can I use the new YT design again or not ?

You can switch back via http://youtube.com/new Make sure to disable the script first, as it breaks the new YouTube.
