About

Extension allows to unscramble (un-uglify) javascript stack traces. Useful if you're developing web applications and need to see what went wrong in live environment.
Options:
1. Select stack trace and click Unscramble context menu.
2. Click on the icon and paste stack trace to the first field and click "unscramble"
Unscrambling is possible only if .map files exist for files in stack trace. Otherwise unsrambling won't lead to more readable results.
