Mozilla Tests an Opt-In AI ‘Smart Window’ in Firefox

Mozilla is testing a new “Smart Window” in Firefox, a separate optional space where users can chat with an AI assistant of their choice while browsing. The feature is being offered through a waitlist and stays off by default. Mozilla says users can decide when, how, or whether to use AI at all, and can turn it off if they do not want it. The company frames the project as user-controlled and says it is building in the open, with feedback from early testers. The Smart Window sits alongside Firefox’s Classic and Private modes, and Mozilla says it is meant to avoid the lock-in it associates with browsers made by AI companies. The feature also extends existing AI tools in Firefox, including the desktop sidebar chatbot and Shake to Summarize on iOS. Mozilla says AI should be “open, accessible, and driven by choice.”

Claude Mythos Found 271 Firefox Flaws as Mozilla Says AI Matches Top Human Researchers

Claude Mythos helped Mozilla uncover 271 Firefox vulnerabilities, all patched in Firefox 150. Mozilla said the model has not shown capability beyond elite human researchers, but its scanning speed sharply changes the economics of vulnerability discovery.

Mozilla report says Chinese models make up 61% of OpenRouter’s top 10 most-used models

Mozilla Foundation released its 2026 State of Open Source AI report in July, led by Mozilla CTO Raffi Krikorian, outlining how quickly open-weight models have narrowed the performance gap with closed systems. According to the report, the capability gap between open and closed models shrank from 8.04% in January 2024 to 0.5% in August 2024, before widening slightly to 3.3% in March 2026 as closed reasoning models improved. Even so, open models have already reached parity in coding and instruction-following tasks, while still trailing in reasoning and long-context performance. The report also points to falling costs and shifting usage patterns. GPT-4-level inference pricing dropped from $20 per million tokens three years ago to $0.40, a 50-fold decline. On OpenRouter, open-weight models grew from roughly one-third of traffic at the end of 2025 to more than half by mid-2026, and the platform’s five highest-traffic models are all open-weight. Mozilla also highlighted China’s growing presence in the segment, saying Chinese models accounted for more than 45% of OpenRouter traffic in April 2026, and 61% of the platform’s top 10 most-used models came from China.
