About this extension

Simple functionality focused add-on used for detecting zero-width characters (invisible characters) which might be used for tracking you online.

Functions:
- Manually preform a scan on a page
- Copy all zero-width characters found
- Specify custom string to replace zero-width characters found (can input nothing to strip them)
- Whitelist domains you trust or that might break from the add-on
- Option for checking any copied text for zero-width characters
- Option to scan a page again when tab becomes active

Release notes for 2.0

Added a new feature and two new options:
- You can now manually preform a scan on a page from the add-ons pop-up menu.
- Option for checking copied text for zero-width characters.
- Option to preform a scan on the page again when the tab becomes active.

These changes should help combat any hidden data inserted dynamically.
