Keyword Filter Extension for Websites

What is Filter Everything Online??

Filter Everything Online is a keyword filter extension that lets you block keywords on websites without blocking the whole site. You can hide or replace matching content across social feeds, news sites, forums, and video platforms, then refine the setup with schedules, site-specific exceptions, and optional account sync.

How does the keyword filtering work??

Our keyword filtering lets you create custom word lists that automatically remove or replace matching content in real time. Start with one focused group, test it on the sites you use most, then refine it with schedules and site-specific rules. For setup examples, see our filter social media Chrome extension guide and our guide to what blocked keywords are and which categories to block first .

Is Filter Everything Online free, and what does Premium offer??

Yes, the extension is completely free to use. The free version includes 3 individual keywords, 1 keyword group with up to 3 keywords, 1 full-site blocking rule, and the default replacement mode. Premium is built for a cleaner internet with less ongoing maintenance, giving you unlimited filters, cloud sync, smart filter modes, and more control over how filtered content gets replaced.

Is the extension regularly updated??

Yes. We constantly update the extension to improve performance, fix bugs, and expand functionality. Better site compatibility and feature requests from users are rolled out regularly. If something breaks, we're usually already working on a fix.

Which browsers are supported??

You can currently install Filter Everything Online through the Chrome Web Store for Chrome-compatible browsers such as Chrome and Brave, through Edge Add-ons for Microsoft Edge, and through Firefox Add-ons for Firefox-based browsers and Android. Safari listing support is rolling out separately. The homepage is now available in 31 languages, and broader page coverage still varies by locale.

Can I filter anything everywhere with this extension??

Yes! Filter Everything Online lets you filter anything everywhere across the internet. Our block keywords extension works on YouTube, Reddit, Twitter, news sites, social media, and virtually any website. You can block keywords, filter profanity, and customize your browsing experience everywhere you go online. If it doesn't work on a website, please let us know so we can improve it.

How does this compare to other filter extensions??

Filter Everything Online focuses on keyword-level filtering instead of all-or-nothing site blocking. You can organize custom keyword groups, schedule filters, add site-specific exceptions, choose hide or replace modes, and keep useful pages accessible while removing recurring noise. For a feature-focused comparison, read our keyword filter extension guide .

Can I sync my filters across devices??

Yes. Premium includes optional account sync, so your keyword filters and settings can stay aligned across your own devices when you choose to sign in. Your core filtering still runs locally in the browser.
