Bash script to customize fresh Firefox and Chrome installation on Linux

Hi all, I need a simple script in Bash, that I can run to customize settings for Mozilla Firefox and Google Chrome fresh installs on CentOS Linux, for each user. I would like to run it as "./[login to view URL] username" In need the script to change these settings, for each browser : - use a blank home page - open new tabs as empty (blank pages) - disable the Proxy - disable SSL Certificate verification - disable any reporting to Mozilla - remove all defined search engines - remove Mozilla account. The budget is $30 max, so if you need more, please do not bid. I will release the money after I successfully test the script for both browsers. Thank you.
