Recently, Mozilla officially released the 150 stable version of the Firefox browser. A major highlight of this update is that Mozilla has collaborated with Anthropic company, using its advanced Mythos Preview AI model to successfully detect and fix 271 security vulnerabilities. This collaboration first began in Firefox version 148, using the Opus 4.6 model, which identified 22 vulnerabilities.

Bobby Holley, Mozilla's Chief Technology Officer, stated that traditional vulnerability detection mainly relied on fuzz testing and manual analysis, which was difficult to cover all types of vulnerabilities. Even if attackers invested a lot of money, they could still find opportunities to exploit vulnerabilities. The application of AI has changed this situation, allowing for more comprehensive coverage of potential vulnerabilities, making software undergo a thorough security check and uncovering hidden issues within the code.

However, this transformation also brings challenges to the open-source software ecosystem. Holley pointed out that many popular open-source projects around the world are maintained by a small number of volunteers, and some projects even face the risk of being unmaintained. Large companies can mobilize thousands of engineers to address these vulnerabilities, but small project maintainers usually have limited resources and struggle to handle the massive workload of vulnerability fixes.

Additionally, Mozilla's CTO Raffi Krikorian also expressed concerns about how AI technology might exacerbate inequality. Critical infrastructure is often maintained by volunteers, while large companies benefit from these services for free. Organizations with abundant resources will gain an advantage in security protection, while relatively weaker projects may face greater risks. To bridge this security gap, Mozilla is actively sharing experiences and tools with the open-source community.
