Firefox is currently the only major browser that still supports the uBlock Origin extension. Other browsers have phased out support, making Firefox unique in this regard. This development impacts users relying on ad-blocking tools.
Firefox remains the only major browser supporting the uBlock Origin extension, after Google Chrome and Microsoft Edge ended support for it earlier this year. This shift affects millions of users who rely on uBlock Origin for ad blocking and privacy, highlighting ongoing changes in extension policies across browsers.
In March 2024, both Google Chrome and Microsoft Edge announced they would no longer support uBlock Origin, citing security and stability concerns. Meanwhile, Mozilla Firefox continues to support the extension, making it the last major browser with active support for uBlock Origin.
The decision by Chrome and Edge was part of a broader move to restrict extensions that could impact browser performance or security. Mozilla has maintained support, citing user demand and the extension’s role in privacy protection, according to Mozilla representatives.
Security experts have expressed concerns over the potential vulnerabilities that could arise from third-party extensions, but also noted the importance of user choice in privacy tools. The future support for uBlock Origin in Firefox remains uncertain, as Mozilla has not announced any plans to change its stance.
Implications for Privacy and Browser Security
This development underscores the shifting landscape of extension support in major browsers. For users, Firefox’s continued support means ongoing access to uBlock Origin, a popular ad blocker that also enhances privacy. Conversely, the discontinuation by Chrome and Edge reduces options for users who depend on such tools, raising questions about the future of extension support and browser security policies.
Industry analysts suggest that browser vendors are increasingly cautious about extension security, which could influence future support decisions. Mozilla’s stance may position Firefox as a preferred platform for privacy-conscious users, but it also raises concerns about the consistency of extension support across browsers.

Background on Extension Support Changes
In recent years, major browsers have tightened extension policies, mainly due to security vulnerabilities and performance issues. Google Chrome and Microsoft Edge, both Chromium-based browsers, have progressively limited support for extensions that modify browser behavior or access sensitive data. The removal of support for uBlock Origin in Chrome and Edge reflects this trend.
uBlock Origin, developed by Raymond Hill, is among the most popular ad-blockers globally, with millions of users. Its support in Firefox has remained stable, with Mozilla emphasizing user choice and privacy. The decision by Chrome and Edge to drop support came after updates to their extension APIs, which restrict certain types of extensions.
As of now, Firefox continues to support uBlock Origin, maintaining its position as a privacy-friendly browser. The situation remains fluid, with ongoing discussions about extension security and user rights across the industry.
“Firefox remains committed to supporting extensions that empower users to protect their privacy and security.”
— Mozilla spokesperson

Next Steps for Users and Industry Stakeholders
Users relying on uBlock Origin should monitor updates from browsers regarding extension support. Mozilla may continue to support uBlock Origin, but this could change if industry policies shift. Browser vendors are likely to revisit extension policies periodically, possibly leading to new support or restrictions.
Industry analysts suggest that the extension ecosystem will evolve, with a focus on security and user control. Advocacy for user choice may influence future policy decisions, but the current landscape suggests ongoing limitations for extension support in Chrome and Edge.

Both browsers cited security and stability concerns as reasons for discontinuing support, aligning with broader efforts to restrict potentially risky extensions.
Will uBlock Origin be supported in other browsers?
Support depends on each browser’s extension policies. Currently, Firefox remains the only major browser supporting uBlock Origin, but future support in others is uncertain.
What are the security risks of using third-party extensions?
Extensions can introduce vulnerabilities if poorly maintained or maliciously designed, but they also provide essential privacy and security functions for many users.
