I'm looking for a way to intercept a POST method to a website and change it's content based on rules.
Given example:
A website is sending a data along with temporary unique identifier. I want to edit only the data I want, leaving the pre-generated identifier as-is.
Example POST:
ageStart=1&ageEnd=19®ions=101&navigator=Near&consent=BOey6KLOey6KLA9ABAPLCN-AAAAmd7
I wish to edit the ageStart and ageEnd variables without touching consent variable which is different every time POST is forged
I'm looking for either the software or a Firefox/Chrome extension
