Current pop-up blockers often block too much, disrupting workflows on sites that rely on pop-ups for essential functions like login forms or help dialogs.
Create a blocker with customizable rules that allows users to define which pop-ups to keep, based on domain or content type.
Monetize through a freemium model where basic blocking is free, but advanced rules and whitelisting require a pro version.
Start with simple domain-based rules and expand to AI-based content filtering later.
The biggest risk is that browser updates might break the extension's functionality or that users won't see enough value to pay for advanced features.
