Firefox Extension

ShimejiFirefox

Tiny browser friends, but for the web. Import a pack, drop a mascot onto the page, and let it wander around your tabs without turning the browser into a mess.

What It Does

ShimejiFirefox lets little mascots scamper across ordinary web pages, idle, bounce, nap, react to reminders, and get dragged around with the cursor. The point is to keep the browser cute without losing control of it.

The extension keeps quick actions in a small popup and the heavier configuration in a proper settings page. Packs are imported manually, so you can choose the characters you actually want instead of getting a bundled dump.

  • Imports Shimeji ZIP packs from creators and community download pages
  • Shows up to two mascots on the same page at once
  • Supports random idle and movement behaviours so they feel alive
  • Lets you drag mascots around directly with the mouse
  • Handles shared alarms and reminders that the mascots react to on-page

Notes

The packs are not bundled into the release. You download them yourself, import them locally, and the rights stay with their original creators and rights holders.

Mascots run on normal websites, not privileged internal browser pages such as about:*. Very large imported collections also take up extension storage, so this is better as a curated set than a hoard.
