The image shows a screenshot of a mobile web browser displaying an article from the Mozilla blog. The article is titled "Firefox Security Response to pwn2own 2025" and is authored by Frederik Braun, dated May 17, 2025. The article discusses Mozilla's commitment to security, mentioning their long-running bug bounty program and mature release management and security engineering practices. It highlights that neither of the two new content-process exploits demonstrated at the pwn2own competition managed to break out of Firefox's sandbox, which is required to gain control over the user's system. The screenshot also shows the browser's status bar at the top, indicating the time as 13:21, the battery level at 91%, and the network signal strength. The URL displayed in the browser's address bar is "blog.mozilla.org/se."
