Sound familiar?

You open YouTube to watch one video and 45 minutes later you're deep in Shorts you didn't ask for.

You check the news for five minutes and surface an hour later feeling worse than before.

You close Instagram, then immediately reopen it out of habit. The feed is designed to keep you there.

It's not a willpower problem. These apps are engineered to hold your attention.
FuseBox gives you the kill switch they won't.

Surgical switches, not blunt blocking

Most blockers are all-or-nothing. FuseBox lets you keep what's useful and switch off what's toxic. Kill YouTube Shorts and recommendations but keep search and subscriptions. Switch off Twitter's trending tab but keep DMs. Remove comment sections everywhere.

Each switch controls one feature. Switch off what you don't need. Keep what you do. It's your internet now.

The strategy

FuseBox works in your browser — not in apps. That's the point.

Delete the apps. Use the web versions instead. Then use FuseBox to switch off the parts designed to keep you scrolling — the algorithmic feeds, the autoplay, the infinite recommendations. You keep the useful parts (messaging, search, your subscriptions) without the addictive ones.

Apps are designed to bypass your self-control. The browser is where you switch it off.

Three steps to take back control

1

Choose what to switch off

Switch off entire categories like Social Media or Streaming. Or drill down — kill just YouTube Shorts, Instagram Reels, or Twitter's trending tab.

2

Delete the apps, install the extension

Remove the apps that hijack your attention. Use the web versions instead, with FuseBox controlling what you see. One click install for Chrome, Firefox, Safari, or Edge.

3

Browse on your terms

Switched-off sites show a friendly page. Distracting features vanish. You're in control — not the algorithm.

Try it yourself

Flip the switches below. Each one controls a category of websites. Drill into any to switch off individual sites and features.
