Plainly por 27mfp

Plainly finds Base64-style coded text on web pages and shows the readable version next to it.

What it does
- Works automatically on Reddit
- Add any other site from the toolbar menu (permission only when you allow it)
- If the decoded text is a link, you can open it
- Copy plain text with one click
- Manual “Try a code” box in the popup
- On/off switch

How to use
1. Install and open Reddit (or add another site)
2. Refresh the tab
3. Look for grey tags next to coded strings
