CPU飙升、电量狂掉，Firefox新AI功能上线即「翻车」，遭老用户怒喷：“跟风加AI简直丢脸”

Core Viewpoint - Firefox's recent update, version 141, introduced an AI feature called "AI Tab Grouping," which has led to significant user dissatisfaction due to increased CPU usage and battery drain [1][2]. Performance Issues - Users reported that the new feature caused a spike in CPU usage and a notable decrease in battery life, with complaints surfacing on platforms like Reddit shortly after the update [2][3]. - A specific process named "Inference" was identified as the cause of high resource consumption, which is linked to Firefox's local AI model operations [3]. AI Feature Implementation - The "AI Tab Grouping" feature aims to automatically identify and name related tabs, operating entirely locally to prioritize user privacy, unlike competitors that utilize cloud processing [4]. - The feature operates in two steps: grouping recognition through an embedding model and automatic naming using Mozilla's smart-tab-topic model [4]. Technical Analysis - The high CPU usage may be attributed to the use of the ONNX format for running local models, which is less efficient compared to other potential formats [5]. - Users have the option to disable the AI features if they experience performance issues, with specific instructions provided for modifying settings [6].
