Questionable Content Extensions is a project to add additional features to the Questionable Content comic.
For now, the only extension made is a user script for Chrome (requires Tampermonkey or equivalent) and Firefox (requires Greasemonkey or equivalent) (untested in other browsers). You can always find the latest version of the script right here.
The source code for the script and its issue tracker can be found on its GitHub project page .
Finally, for broader discussions about the extension, please come visit the subreddit .
