Mozilla's AI Shake to Summarize is announcing itself via a blue dot in the menu and a pop-up when you visit articles. Neither the popup, the confirmation dialog, nor the new menu item mention AI.
I find it effective for 'feedback' (bug reports/feature requests) sometimes because it can automatically screenshot parts of the app that wouldn't typically have a UI to send feedback on it, for example a menu, where a feedback option listed in the menu would always capture what's behind the menu instead.
Of course it would be even easier if I could just upload screenshots I manually took myself, but Google hates that idea apparently.
