🐾 Yasenka — Browser Pet

A tiny catgirl named Yasia lives right on top of any web page. She walks and runs along the page structure, can be dragged around and thrown, and you can pet and feed her. Two real superpowers under the hood:

• 📥 Download videos from the page — YouTube, TikTok, Twitter / X and Instagram.
• 📝 Notes & links — jot down quick notes and links, saved locally in your browser.

The interface is English by default. Press the RU button (in Yasia's speech bubble or in the popup) to switch to Russian — and back.

✨ Features

📥 Video downloader

Click Yasia → Download video from the page. She grabs the video from the current page:

Platform	Notes
YouTube	Quality = whatever the player has loaded (set 1080p in the player, let it buffer a bit, then download).
TikTok	The active clip from the feed, without watermark.
Twitter / X	The video from the open post.
Instagram	The active reel / post video.
Other sites	Any direct video on the page (best-effort).

For TikTok / Instagram you can also paste a clip link into the field and download exactly that one.

📝 Notes & links

Click Yasia → Notes & links. Type any text or link, hit Save — it stays in chrome.storage.local. Links become clickable.

🐱 The pet itself

• Lives on any site, walks and runs across the page by default.
• Drag & throw her around — she flies with inertia and lands on page elements.
• Feed her meat from the popup; she gains XP and levels up (bigger & livelier).
• On X (Twitter) she walks up to posts and asks for a like — the like is placed only when you click the pet. No auto-actions, no automation.
• One setting: Size (default 180%). EN / RU language toggle.

🚀 Install (developer mode)

Firefox (Mozilla)

1. Type about:debugging in the address bar.
2. Open This Firefox.
3. Click Load Temporary Add-on…
4. Select the manifest.json file in this folder.

Chrome

1. Open Manage extensions (top-right menu → Extensions).
2. Turn on Developer mode (top-left toggle).
3. Click Load unpacked, open this folder and confirm.
4. Reload any already-open tabs — the extension is injected on page load, so it won't appear in old tabs until you refresh them.

A 🐾 button shows up at the bottom-right of the page — click it to show/hide Yasia.

After editing the code: on chrome://extensions hit ↻ on the extension card, then reload the website tab.

🔒 Safety principle

Real actions on X happen only as a direct response to your click on the pet (one click = one deliberate like, at human speed). Everything else is a visual layer on top of the page — it never changes content and never sends anything out.
