As Backend Developer on Odoo, we know that print, PDB and all the other python debug tools are our best friends when trying to achieve our coding and debugging tasks. Unfortunately, we usually forget one of the best tools that are available to us: The browser's debugger.   

First, you will learn how to find useful information with this tool. Then, you will see how this information can help you  

- debug your python code  

- understand how Odoo works  

- find out where any transaction starts  

- find out why the web client is complaining    

At the end of this talk, you'll be convinced that your browser's debugger is the best starting point for all your investigation.
