Firefox surprises no one by adding AI to the browser

Firefox 135 debuts today, with (what else?) AI built right into the browser. Unlike Microsoft Edge and Copilot or Brave's own Leo AI chatbot, Firefox isn't investing in its own AI capabilities. Instead, the company is building in AI access to third-party chatbots such as Anthropic's Claude and ChatGPT, plus lesser-known LLMs like HuggingChat and Le Chat Mistral. As of a week ago, this AI capability was labeled "experimental" and was being pushed to a small part of the Firefox user base. Now, the Firefox release notes state that it's being pushed out gradually to all users.
