Get Rid of it With a User Script (Firefox or Chrome)
If you’re using Firefox and you want to get rid of this bar, you can use a user script along with the Greasemonkey extension. If you’re using Google Chrome, user script support is built right in and all you have to do is head over to this user script and click the Install button.
To uninstall the user script, use the Tools menu and find the Manage Extensions option, or type in chrome://extensions into the location bar.
Once there, find the item called “Subscription Bar” and click the Uninstall button.
Use a Google Chrome Extension
If you’d rather, you can use a Google Chrome extension instead, though you should note that Chrome extensions use more memory than user scripts, since they run as a separate process for each extension.
You can uninstall it the same way as the user script.

Change the URL (for Sharing With Others)
If you’re planning on sending the video to other people and don’t want them to have to see the autoplay bar either, you can simply remove part of the URL before you send it over.
Just highlight everything from &playnext= all the way to the end of the URL, hit the Delete key, and then copy the rest.
What do you think? Does the Autoplay bar annoy you?
