Yes, there are two workarounds!
One I advise is installing Tampermonkey for Chrome.
Tampermonkey is an extension to manage userscripts with chrome. With that you can install userscripts from any site and they won't mess up your extension-list as they are listed within the Tampermonkey-overview.
To install userscrpts the old way, you need to download the userscript into a file and open the extension-list within chrome. Dragging the file into the extension-list will install it as a new extension. However, classic GM-functions won't work, so some scripts may not work that way.
