The Firefox 148 AI kill switch is now live as Mozilla delivers on its promise to give users full control over artificial intelligence features inside its browser. Following criticism over plans to expand AI integration, Mozilla has introduced a one click option that disables all AI enhancements in Firefox 148.
The update confirms that users can either selectively manage individual AI tools or completely block them using a centralized toggle.

Mozilla Responds to AI Concerns
When Mozilla first announced its plan to position Firefox as an AI powered browser, reactions were mixed. While some welcomed productivity improvements, others raised privacy and user control concerns.
In response, Mozilla pledged to implement a kill switch that would allow users to turn off AI features entirely. With the release of Firefox 148, that promise has now been fulfilled.
Users can activate the “Block AI enhancements” toggle to prevent AI related pop ups, reminders, and features from appearing in the browser.
AI Features Included in Firefox 148
Firefox 148 introduces several artificial intelligence tools aimed at improving browsing, accessibility, and productivity.
Built In Translations
The browser now includes translation tools that help users browse websites in their preferred language without relying on external extensions.
Alt Text in PDFs
AI generated alt text is added to images within PDF files, improving accessibility for screen reader users.
AI Enhanced Tab Grouping
Firefox can now suggest related tabs and recommend group names, helping users manage multiple open pages more efficiently.
Link Previews
The browser provides AI generated summaries or key highlights before users open a link, offering context without leaving the current page.
Sidebar AI Chatbot Integration
A major addition is the AI chatbot in the sidebar. Users can choose from several supported services, including:
-
Anthropic Claude
-
OpenAI ChatGPT
-
Microsoft Copilot
-
Google Gemini
-
Mistral AI Le Chat
This integration allows users to interact with AI assistants while browsing without switching tabs.
How the AI Kill Switch Works
The Firefox 148 AI kill switch can be accessed directly through the browser settings menu. Users who want to disable all AI tools can turn on the Block AI enhancements toggle.
When activated:
-
AI pop ups are removed
-
Feature prompts are disabled
-
AI sidebar suggestions are hidden
-
Future AI reminders will not appear
For users who prefer more control, individual AI tools can be switched off separately instead of enabling the full kill switch. This ensures flexibility for those who want selective AI functionality.
Telemetry Data Collection
Mozilla has confirmed that it will collect telemetry data on how many users activate the Firefox 148 AI kill switch. According to documentation referenced on Bugzilla, the data will help assess user adoption rates and overall reception of AI features.
The organization has not yet published the complete official release notes for Firefox 148, but they are expected to be made available on its website.

What This Means for Firefox Users
The release of the Firefox 148 AI kill switch highlights Mozilla’s effort to balance innovation with transparency and user autonomy. While AI powered features are becoming standard in modern browsers, Mozilla is emphasizing opt in control.
Users who want AI assistance can take advantage of enhanced tab management, link previews, chatbot access, and accessibility improvements. Those who prefer a traditional browsing experience can disable everything with a single setting.
As AI integration continues to evolve across the tech industry, Firefox 148 positions itself as a browser that prioritizes user choice alongside new technology.
