TL;DR
Firefox is now the last major web browser to support the uBlock Origin ad blocker extension. Other browsers have discontinued support, raising questions about extension policies and user privacy.
Firefox is now the last major web browser that continues to support the uBlock Origin extension, a popular ad blocker used by millions. This development matters because other leading browsers, including Google Chrome and Microsoft Edge, have recently discontinued support for uBlock Origin, raising questions about the future of extension support and user privacy protections in those platforms.
Support for uBlock Origin in Firefox persists despite widespread changes in browser extension policies. Mozilla, the organization behind Firefox, confirmed that the extension remains available and supported on its platform, citing a commitment to user choice and privacy. In contrast, Google Chrome and Microsoft Edge have officially removed or restricted support for uBlock Origin, citing security and policy concerns. This shift marks a significant divergence in how major browsers handle third-party extensions, especially ad blockers.
Industry experts note that the decision by Chrome and Edge to limit support may be driven by concerns over extension security, malicious code, or platform control. Mozilla has maintained a more open approach, emphasizing user autonomy. The developer of uBlock Origin, Raymond Hill, confirmed that the extension still works in Firefox but is no longer supported in Chrome and Edge, which have phased out extension support or limited it through stricter policies.
Implications for User Privacy and Browser Policy
This development underscores the ongoing debate over extension policies and user privacy. Firefox’s support for uBlock Origin allows users to continue blocking ads and trackers, reinforcing its reputation as a privacy-focused browser. Conversely, the removal of support in Chrome and Edge could limit user control over ad-blocking and privacy tools, potentially impacting millions of users who rely on extensions like uBlock Origin for online privacy and security.
Furthermore, this divergence highlights broader industry tensions between platform control, security concerns, and user rights. Mozilla’s stance supports open extension ecosystems, while Chrome and Edge’s restrictions reflect a move toward tighter platform regulation.

Recent Changes in Browser Extension Support Policies
Over the past year, major browsers have tightened extension support policies. Google Chrome and Microsoft Edge, both based on Chromium, have implemented stricter extension vetting processes, leading to the removal or restriction of several popular extensions, including uBlock Origin. These changes are partly driven by security concerns, with platforms aiming to prevent malicious extensions from compromising user devices.
Firefox, meanwhile, has maintained a more permissive approach, allowing extensions like uBlock Origin to remain available. Mozilla has emphasized its commitment to user choice and privacy, resisting some of the restrictions adopted by Chromium-based browsers. The decision to support uBlock Origin in Firefox reflects this stance and the extension’s popularity among privacy-conscious users.
“Firefox remains committed to supporting extensions that prioritize user privacy and security.”
— Mozilla spokesperson
Unclear Future of Extension Support in Major Browsers
It is not yet clear whether other browsers will follow Chrome and Edge in restricting support for extensions like uBlock Origin. While Firefox continues to support it, the long-term policy trajectory in Chromium-based browsers remains uncertain, especially as platform security and control concerns evolve. Additionally, some users and privacy advocates question whether future updates could further restrict or remove support for popular extensions across all browsers.
Next Steps for Users and Developers
Users relying on uBlock Origin in Chrome and Edge may need to consider alternative privacy tools or switch to Firefox for continued support. Developers of ad-blocking extensions may also face increased restrictions or need to adapt to new policies. Industry observers will be watching whether other browsers reconsider their extension policies or if Mozilla’s support for uBlock Origin influences broader industry standards.
Meanwhile, Mozilla is expected to reinforce its commitment to open extension ecosystems, potentially advocating for more flexible policies in Chromium-based browsers. The future of extension support in major browsers will likely depend on ongoing security debates and platform control considerations.
Key Questions
Why is Firefox still supporting uBlock Origin while Chrome and Edge are not?
Firefox maintains a more open extension policy emphasizing user choice and privacy, whereas Chrome and Edge have restricted extension support to improve security and platform control.
Will uBlock Origin or similar extensions be supported in other browsers?
It is uncertain. Some browsers may follow Chrome and Edge’s lead, while others, like Firefox, may continue supporting such extensions or develop alternative policies.
How does this affect user privacy?
Support in Firefox allows users to continue blocking ads and trackers effectively, while restrictions in Chrome and Edge could limit access to these privacy tools for some users.
Are there security risks with supporting extensions like uBlock Origin?
Both sides argue about security; some claim extensions can introduce vulnerabilities, while supporters say they are essential for privacy and security when properly maintained.
