Best Profanity Filter Chrome Extensions

Not every profanity filter works the same way. Some send page text to a server, some slow down browsing and some cannot be customised at all. We compared the best profanity filter Chrome extensions by privacy, customisation, performance and coverage, including PureWord.

How we compared them

Each extension was judged on four things: whether filtering runs locally in the browser, how much you can customise the word list and mask style, the impact on page load times and which parts of a page are covered, including dynamically loaded content such as comments.

Privacy first

The biggest difference between extensions is where filtering happens. The best ones process text locally in small chunks and never send your browsing content anywhere. Choose one like PureWord that states clearly that filtering runs entirely in your browser.

Customisation

Look for custom word pairs, a choice of mask styles such as asterisks, first letter or blur, per page toggles and the ability to block a word directly from any page with a right-click. PureWord and Advanced Profanity Filter both support custom words, and PureWord also lets you block a word directly from any page with a right-click.

Performance and coverage

The best filters have a negligible impact on page load times because filtering runs locally in small chunks. Coverage matters too: comments, search results, video titles and dynamically loaded text should all be filtered, not just the static article text.
