Quick Overflow

Every time Quick Overflow detects an error in your JavaScript, it embeds an "error module" at the top of your webpage.
This module contains:
• an explanation of your error
• the code that caused it
• a one-click Stack Overflow search for relevant solutions.

The extension can listen for errors on any website, but can also be easily disabled for when you want to browse the web in peace.

*IMPORTANT*
Click the icon to enable the extension, and make sure to "Allow access to file URLs" by visiting chrome://extensions. This allows the extension to listen for errors when you are developing locally.
