TL;DR
Firefox continues to support uBlock Origin, making it the last major browser with this extension. Other browsers like Chrome have dropped support, raising concerns about ad-blocking options.
Firefox is now the last major browser that still supports the popular ad-blocking extension uBlock Origin, following its removal from browsers like Chrome and Edge. This development underscores ongoing shifts in browser extension support, affecting users who rely on ad-blocking tools.
Support for uBlock Origin in Firefox continues despite widespread removal from other major browsers, including Google Chrome and Microsoft Edge. Mozilla confirmed that the extension remains available in the Firefox Add-ons store, and users can install and update it normally. The extension’s developer, Raymond Hill, stated that Firefox’s support is due to Mozilla’s open extension policy and its compatibility with the WebExtensions API.
In contrast, Chrome and Edge have phased out support for many third-party extensions, citing security concerns and platform changes. Google announced in 2022 that extensions using the legacy extension APIs would no longer be supported, leading to the removal of uBlock Origin and similar extensions from Chrome Web Store. Microsoft Edge followed suit, aligning with Chrome’s policies after switching to Chromium.
This shift has left many users dependent on uBlock Origin questioning their options, as other browsers like Safari and Opera have also limited extension support or require manual installation methods. Mozilla’s continued support for uBlock Origin in Firefox is seen as a significant exception in the current browser landscape.
Implications for Users Relying on Ad-Blocking Tools
This development matters because uBlock Origin is one of the most popular and widely trusted ad-blocking extensions, with millions of users globally. Its support in Firefox ensures that users who prioritize ad-blocking have a viable option, especially as other browsers have discontinued support. It also highlights differences in browser policies regarding extension security and user choice, which could influence future browser development and user trust.
For privacy advocates and those concerned about online tracking and intrusive ads, Firefox’s support offers a measure of continuity. However, the trend away from extension support in Chrome and Edge raises broader questions about the future of customizable browsing and third-party extension security standards.

Browser Extension Support Trends and Policy Changes
Over the past few years, major browsers have shifted their extension policies. Google Chrome, the most widely used browser, announced in 2022 that it would phase out support for legacy extension APIs, effectively removing many extensions, including uBlock Origin, from the Chrome Web Store. Microsoft Edge, which switched to Chromium, adopted similar policies, leading to the removal of many extensions from its store.
Mozilla Firefox, however, has maintained a more open approach, supporting extensions via the WebExtensions API, which is compatible with Chrome’s extension system. This has allowed Firefox to retain support for popular extensions like uBlock Origin, despite the broader industry move towards stricter extension security standards and platform restrictions.
This divergence underscores ongoing debates about extension security, user privacy, and the balance between platform control and user choice in web browsers.
“Firefox continues to support uBlock Origin because of its open extension policy and compatibility with WebExtensions.”

Remaining Extension Support in Other Browsers Still Unclear
It is not yet clear whether browsers like Safari or Opera will follow Firefox’s lead in supporting uBlock Origin or similar extensions, or if they will implement their own restrictions. Additionally, the long-term viability of extension support in Chrome and Edge remains uncertain as platform policies evolve.

Potential Changes in Browser Extension Policies and User Options
Moving forward, users relying on uBlock Origin and similar extensions will need to monitor updates from browser developers regarding extension support. Mozilla may continue to champion open extension policies, but other browsers might tighten restrictions, potentially reducing user control over browsing customization. The extension developer community may also seek alternative solutions or platform support to maintain functionality across browsers.
