Are coupon extensions hijacking my checkout and lowering conversion?

I'm experiencing significant issues with coupon extension apps and browser plugins that seem to be interfering with my Shopify store's checkout process. These extensions automatically apply random discount codes, create unnecessary friction, and I suspect they're negatively impacting my conversion rates. I want to understand how these extensions work, their potential impact on my store's performance, and what strategies I can implement to mitigate their disruptive effects on the customer journey and overall sales funnel.
