Perplexity in Firefox Changes Everything: What Developers Need to Know About Browser-Native AI Search

Perplexity AI is now a native search option in Firefox's address bar, and this single integration will funnel millions of users away from traditional search results into AI-generated answers that cite only 3 to 5 sources per query. If you build websites, apps, or content for the web, this affects you directly. Here's why, and what you can do about it.
