Recently, after the release of the latest version of Mozilla Firefox, users have been reporting that the newly added multiple artificial intelligence (AI) and large language model (LLM) related features have sparked widespread attention and controversy. These new features are enabled by default after installation, and users may not be aware of them while using the browser, causing concerns about privacy and performance for many users.

According to user tests, enabling these local AI features caused a significant increase in CPU and memory usage in Firefox, affecting the browsing experience. Moreover, many users said that it was difficult to find direct options to disable these features in the browser settings, which caused confusion and frustration. In addition, some technical users expressed dissatisfaction with the wording in Firefox's terms of service regarding data usage, believing there were potential privacy risks.
To address this situation, some users have actively explored adjustments in the browser settings. They found a series of configuration options to disable AI features by accessing the "about:config" page, including "browser.ml.enable" and "browser.ml.chat.enabled", among others. Some users even wrote batch disable scripts to conveniently turn off these unnecessary features across multiple Firefox profiles with one click.
Although Firefox has always been committed to providing a user-friendly experience, this approach of forcing AI features to be enabled may negatively impact its performance in the market. Currently, Firefox's market share is less than 3%, and industry opinions suggest that pushing these default AI features may further reduce the popularity of the browser among regular users.
Key points:
🌐 The new version of Firefox enables AI features by default, causing disputes over user privacy and performance.
⚙️ User feedback indicates increased CPU and memory usage, and difficulty in disabling the features.
🔧 Technical users adjust settings through about:config and use batch disable scripts to turn off AI-related features.
