Why would I use it?
Some people feel that website comments are an annoyance or distraction from the main content. Some choose to use shutup.css to avoid being drawn into protracted arguments or avoid being exposed to statements that instill anger or sadness in them.
How do I install it on my computer?
The simplest way to use shutup.css on a conventional desktop or laptop computer is with a browser extension. There are official extensions available for all mainstream browsers:
- Shut Up for Chrome
- Shut Up for Safari (Shared link for macOS, iOS, and iPadOS)
- Shut Up for Firefox
- Shut Up for Edge
- Shut Up for Opera
These extensions by Ricky Romero automatically update themselves with the latest shutup.css stylesheet, and allow you to toggle comment blocking on and off with a toolbar button.
Shut Up for Safari on macOS requires macOS Sierra or later.
If you don't want a separate extension, you can instead use the Stylus plug-in, in combination with the raw shutup.css stylesheet (detailed below).
Installation on Opera
Shut Up works well on Opera, but you have to install it from the Chrome Web Store. Here's how:
- Go to the page for Shut Up on the Chrome Web Store.
- Click the "Install Extension" button that appears under the address bar.
- After the page reloads, click the "Add to Opera" button.
- Dismiss the compatibility notice, which takes you to Opera's settings page for Shut Up.
- Click the Install button.
Though Opera has an official add-ons website, Shut Up can't be listed there due to months-long approval cycles.
How do I install it on my iPhone or iPad?
You must have a 64-bit device running iOS/iPadOS 9 or later.
The following content blocker apps include shutup.css:
- Shut Up by Ricky Romero (Shared link for macOS, iOS, and iPadOS. Requires iOS/iPadOS 12 or later)
- Content Blocker+ by Dynamic App Design LLC
How do I install it on an Android device?
Shut Up was previously available for Firefox on Android. However, the most recent update (as of late August 2020) removed compatibility with almost all Firefox extensions. Please tell Mozilla what you think of these changes.
Do I have to use an extension or plug-in?
shutup.css can be used in any web browser that allows the loading of custom user stylesheets. Most popular browsers do for accessibility reasons; for example, to allow a visually impaired user to make text larger.
To use shutup.css as a custom user stylesheet:
- Download the auto-updating shutup-user-stylesheet.css file to your system.*
- In your browser's preferences, configure your browser to use shutup-user-stylesheet.css as a custom user stylesheet. In Safari for Mac, for example, it looks something like this:
After selecting "Other..." from the pop-up menu, select the shutup-user-stylesheet.css file you downloaded in step 1. This process will vary in other browsers, but the general idea is the same.
If you make changes to the stylesheet, or download a new version of shutup.css, you may need to quit and restart your browser to make sure it takes effect.
*If you don't trust a remotely-imported CSS file being applied to every web page you see, or if you want to make additional customizations, you can download the most recent non-updating version instead, but you will have to occasionally update this file manually.
How about a bookmarklet instead?
Another option is to install the shutup.css bookmarklet. The bookmarklet lives in your bookmarks toolbar, and applies the shutup.css stylesheet only when you click on it rather than automatically when pages load.
The bookmarklet can be installed by selecting the text below and dragging it into your browser's bookmark bar:

Anything I should watch out for?
shutup.css works by looking for blocks of content on the page that are identified in the page's source code as "comments" or similar identifiers. The stylesheet instructs the web browser to simply not display these blocks.
This may affect some web applications in unexpected ways. I'm told it hides the "discussion" section of Bugzilla installations, for example. Remember to try disabling shutup.css if you think you might be missing important page content.
What about privacy?
Stylesheets like shutup.css contain no executable code, so they cannot track or spy on you.
