How do I measure conversion impact from disabling coupon extensions?

As an e-commerce manager, I'm concerned about how third-party coupon browser extensions might be impacting my store's conversion rates and profit margins. I want to understand the precise methodology for measuring the conversion impact when these extensions are disabled, including what metrics to track, how to set up a controlled experiment, and what statistical significance looks like in this context. My goal is to make a data-driven decision about managing these potentially revenue-draining browser add-ons.
