About this extension
★ Update Information ★
・A new cat now appears at random!
・You can now add any target sites you like!
※ On sites with frequent page changes or reloads, tracking may reset more easily.
We recommend using this on social media, video sites, or other services where you stay on the same site for a while.
※ If the display or behavior becomes unstable after updating, please reload the open page once.
———————————————————
Social media is just too hard to stop checking, isn't it? 💦🥵
What you need isn't more willpower — it's a cat that forces its way onto your screen!!
You know that cat who always shows up right when you're trying to work? 🐈️
We've recreated that classic cat-owner experience in your browser.
Oh well, they're too cute to stay mad at.
Let's face it — humans are just servants to their cats.
We are powerless against their charm.
The supreme beings. The ultimate fluffballs.
Let their adorableness heal you while you take a proper break.
■ Who this is for
* The scrolling won't stop
* You suddenly realize an hour has passed
* Willpower alone just isn't cutting it
■ How to use
1. Set your usage limit (default: 30 min)
2. Set your break time (default: 5 min)
3. Set your favorite sites (default: major social media sites)
4. When time's up, a cat appears
5. Rest until the countdown ends
■ How it works
* Only counts time when a target site tab is active
* Tracking resets when you switch to another tab or app
* After your break, the usage timer starts again
■ Supported Sites
The default settings include major social media sites.
You can add, remove, or change target sites from the menu.
Note: Tracking may reset on sites with frequent page changes or reloads, so Cat Gatekeeper works best on social media and video sites where you stay on the same service for a while.
