Can I set content.js go first, before scripts from page? Chrome Extension

Add-ons Development
#1

On website I have .on('click') and on my content.js I have addEventListener('click') both for same button.

If I click on the element, script from website Jazz monthly internet packages is execute before my content.js script , on my manifest I have "run_at": "document_end" , I can’t set it to document_start because have to wait for DOM to be ready.

Is it possible? Or any tips to accomplish this task?
