LinkedIn Downvote Engine
Chrome extension that adds a native downvote button to LinkedIn, letting you grey out or hide posts you don't want in your feed.
LinkedIn has a like button but no downvote. This extension adds one — a native downvote on every post that lets you grey out or hide the things you'd rather not see, so your feed drifts toward what you actually want.
How it works#
LinkedIn's feed loads asynchronously and never stops re-rendering, so the button
is injected through a MutationObserver that keeps up as new posts stream in on
infinite scroll. There's no server: the posts you've downvoted and your filter
preferences are kept locally in Chrome Storage. It's open-source, with 10+
weekly users.
The code is on GitHub.
