MySocial Browser Extension
Detect supported social posts directly from your browser and jump straight into the right MySocial tool.
What it does
On a supported YouTube, Reddit or Instagram page, the extension detects it and runs three tools natively - no redirect to the website:
- Pick Winner - fetches comments and runs the same signed, cryptographically verifiable draw as the website.
- Get Thumbnail - works for any platform now, not just YouTube.
- Download Video - Reddit, Vimeo, Instagram, direct links, and most other webpages.
It calls MySocial’s own backend directly for these, never a third-party site, and never holds an API secret itself; anything requiring one (Reddit, Vimeo) stays server-side.
YouTube video download works differently
YouTube has no official download endpoint, and its anti-bot check rejects requests that aren’t a real browser - so this can’t be done server-side (see the website’s Video Downloader for why). Instead, while you watch a video, the extension observes the stream URLs your own browser’s player already requested and was legitimately served, and offers those for download. A quality is only downloadable once you’ve actually played the video at (or near) it - that’s a real constraint, not a bug.
Manual installation
The extension isn’t in the Chrome Web Store or Edge Add-ons store yet. Until it is, install it as an unpacked developer extension:

- 2Open chrome://extensions (or edge://extensions in Edge).
- 3Enable "Developer mode" (top-right toggle).
- 4Click "Load unpacked" and select the /extension folder.
