Startled Reminder от Dolla

Startled Reminder is a light and friendly Firefox addon that gently nudges you to take a break when you've been browsing the same webpage for too long. If you stay on a single page for more than 30 minutes, a cute on-screen message will appear:
"You've been here a while... maybe it's time for a little break? 😊"
Designed with mindfulness in mind, this addon helps reduce eye strain and boost productivity by reminding you to pause, stretch, or simply breathe. It’s perfect for those who often get lost in deep reading, endless scrolling, or research marathons.
Let Startled Reminder take care of your well-being while you surf the web!
