TL;DR
Firefox is now the last major browser to support uBlock Origin, a widely-used ad blocker extension. Other browsers have phased out support, making Firefox unique in this regard. The move impacts users relying on uBlock Origin for ad blocking and privacy.
Firefox is now the only major web browser that continues to support the popular ad blocker extension uBlock Origin, after other leading browsers phased out support for certain extensions. This development underscores Firefox’s unique position among mainstream browsers in maintaining compatibility with privacy-focused tools, which is significant for users relying on uBlock Origin for ad blocking and privacy protection.
According to Mozilla, Firefox has preserved support for uBlock Origin in its latest versions, despite other browsers like Google Chrome, Microsoft Edge, and Apple Safari discontinuing support for certain third-party extensions or restricting their functionality. This move makes Firefox the last major browser where users can install and run uBlock Origin without additional workarounds or compromises.
Industry analysts note that this shift reflects broader changes in browser extension policies, particularly Chrome and Edge’s move towards stricter extension security and privacy controls. Mozilla has emphasized its commitment to user privacy and open web standards, which partly explains its continued support for extensions like uBlock Origin.
Impact on Privacy and Extension Ecosystem
This development matters because uBlock Origin is one of the most popular ad blockers globally, used by millions to reduce online ads and enhance privacy. Firefox’s support ensures continued access to this tool, supporting user control over online privacy. Conversely, the phasing out of extension support in other browsers limits user options and may lead to increased reliance on less customizable or less privacy-focused solutions.

Broader Industry Shift Away from Extension Support
Over the past year, major browsers like Chrome and Edge have implemented stricter extension policies, including limiting the types of extensions allowed and reducing support for legacy or third-party extensions. Google Chrome, in particular, has prioritized security and performance, which has resulted in the removal or restriction of some extensions, including ad blockers.
Mozilla’s decision to maintain support for uBlock Origin is viewed as a stand for user privacy and open web principles. Historically, Firefox has been more permissive with extension support, but this is now increasingly rare among mainstream browsers.
“Firefox remains committed to supporting extensions that empower users to protect their privacy and customize their browsing experience.”

Future of Extension Support in Major Browsers
It is still unclear whether other browsers will reintroduce support for popular extensions like uBlock Origin or if Firefox’s support will be maintained long-term as browser policies evolve. The industry trend toward stricter extension security could lead to further restrictions or changes in how extensions are supported across all major browsers.
