White Mirror

White Mirror is a tool which filters the negativity-biased Internet. Available for Firefox (desktop and mobile) and Chrome (desktop).


  1. Download the Greasemonkey (Firefox) or Tampermonkey (Chrome, Edge, Safari, Opera Next) browser extension.
  2. Click here, then click Install on the prompt.
  3. Customize the userscript to suit you. (Currently not user-friendly - I'm busy simplifying this.)

What does it do?

White Mirror hides elements on webpages which contain certain keywords. It is very fast and should not impact performance. You choose which keywords go into the list.

It includes two lists of terms ("bad" and "worse"). By default, elements containing "bad" words are reduced to 25% opacity, while elements containing "worse" words are reduced to 0% opacity. Sites will have empty spaces in them due to content being redacted.

Can I exclude certain websites?

Yep! Click the Greasemonkey icon, click options, and click the line below the box (starting with +) to add the current website to the exclude list.

How do I get rid of it?

Uninstall the Greasemonkey/Tampermonkey browser extension.

Why did you make it?

I was tired of scrolling past headlines like "14-year-old girl gang-raped in field by four men". Every time I did, it ruined my day and made me miserable. I don't want to become the kind of insensitive which lets you read that and shrug it off. But I like being connected to the rest of the world via the Internet. So I decided to write a filter.

Isn't this censorship?

It's optional and self-inflicted.

So, stick your head in the sand?

If you want to look at it that way, sure. Read the section entitled "Pessimism" on defetter.com for my views.
