TL;DR
Firefox is now the only major browser that continues to support uBlock Origin. Other browsers have phased out support, raising questions about extension compatibility and security.
Firefox is now the last major web browser supporting the uBlock Origin extension, after Google Chrome, Microsoft Edge, and other browsers discontinued support earlier this year. This development affects millions of users relying on uBlock Origin for ad blocking and privacy, highlighting ongoing shifts in extension support and browser policies.
Support for uBlock Origin, a widely used ad blocker, was officially dropped by Google Chrome and Microsoft Edge earlier this year due to changes in extension policies and security concerns. Firefox, however, continues to support the extension through its WebExtensions API, making it the last major browser to do so.
Mozilla confirmed this support in a statement, emphasizing their commitment to user choice and privacy. “Firefox remains dedicated to supporting extensions that enhance user privacy and control,” a Mozilla spokesperson said. The extension’s developer, Raymond Hill, also confirmed continued compatibility with Firefox, citing ongoing support and updates.
Impact of Firefox’s Unique Support for uBlock Origin
This development is significant because it positions Firefox as the sole major browser maintaining support for a key privacy tool, potentially influencing user choice and extension development. It also underscores the shifting landscape of extension support, with other browsers prioritizing security and performance over extension compatibility. For users, this means continued access to uBlock Origin on Firefox but increasing limitations elsewhere, which could impact privacy and browsing experience.

Background on Extension Support Changes in Major Browsers
Earlier this year, Chrome and Edge announced plans to phase out support for certain legacy extensions, citing security and performance concerns. These changes followed updates to their extension policies, including restrictions on API usage and sandboxing requirements, which many extensions could not meet. As a result, popular extensions like uBlock Origin were removed from their stores, leaving Firefox as the last major browser supporting it.
Firefox has historically maintained a more permissive extension environment, allowing continued support for tools like uBlock Origin, which is highly valued for privacy and ad blocking. This divergence highlights differing priorities among browser vendors: security and stability versus user control and customization.

Remaining Questions About Extension Support and Future Changes
It is not yet clear whether other browsers might reintroduce support for uBlock Origin or similar extensions in the future. The long-term sustainability of extension support on Firefox also remains uncertain, especially if security policies evolve. Additionally, the impact of this support on user privacy and whether other extensions will follow suit is still developing.

Next Steps for Users and Extension Developers
Firefox users will continue to have access to uBlock Origin, but extension developers may face challenges as browser policies evolve. Mozilla has indicated ongoing support, but users should stay informed about potential policy changes. Extension developers may also seek to adapt their tools to meet new security standards or explore alternative support strategies across browsers.
In the coming months, updates from Mozilla and other browser vendors could influence the extension landscape further, potentially affecting user privacy tools and customization options.
