Extension Usage Instructions

                        F12 is an all in one developer toolbox. It tries to give you all the tools that you need as a developer. 

We currently have:

Unix time converter + timezone converter, 
JWT Decoder, 
Base64 Encoder / Decoder, 
URL Inspector / Constructor, 
KeyCode Finder and 
JSON Formatter. 

We're working on adding more tools in near future.

Our aim is to provide a safe set of tools where your sensitive data doesn't leave your browser. You don't have to paste your JWT into that fishy website ever again.
