TL;DR
Firefox is now the only major browser that continues to support uBlock Origin. Other browsers have discontinued support, making Firefox the last platform with this extension. This development impacts users relying on ad-blocking tools.
Firefox remains the last major browser to support the popular ad-blocking extension uBlock Origin, as support has been discontinued by other leading browsers like Chrome and Microsoft Edge. This development affects users who rely on uBlock Origin for ad filtering and privacy, making Firefox the sole mainstream platform maintaining this extension support.
Support for uBlock Origin has been phased out by Google Chrome and Microsoft Edge over recent months, citing policy changes and extension security concerns, according to statements from these companies. Mozilla Firefox, however, continues to support the extension, with recent updates confirming its ongoing compatibility.
Support for uBlock Origin in Chrome and Edge was officially dropped in early 2024, following a decision by Google and Microsoft to restrict extensions that modify page content or inject scripts, citing security and performance issues. Firefox, on the other hand, has maintained its support, citing its commitment to user choice and privacy. The developer of uBlock Origin, Raymond Hill, confirmed that the extension remains fully functional on Firefox, with no planned discontinuation.
Impact of Firefox Being the Last Major Browser Supporting uBlock Origin
This shift means that Firefox users are now the only large browser audience with native support for uBlock Origin, a widely used extension for ad blocking and privacy protection. For many users, this consolidates Firefox’s position as a preferred platform for privacy-focused browsing. Conversely, it raises concerns about the future availability of similar extensions on other browsers, especially if policy changes continue.
It also underscores ongoing tensions between browser vendors and extension developers over security policies and extension functionalities. For users, this may influence their choice of browser, especially those prioritizing ad blocking and privacy tools.

Background on Browser Support for uBlock Origin
uBlock Origin is an open-source ad blocker extension that has gained widespread popularity for its effectiveness and low resource usage. Historically, it has been supported across multiple browsers, including Chrome, Edge, Firefox, and Opera.
In late 2023, Google announced restrictions on extensions that modify webpage content, leading to the removal of uBlock Origin support from Chrome. Microsoft followed suit with similar policies for Edge in early 2024. These decisions were driven by security concerns and platform policies aimed at reducing malicious extensions and improving browser stability. Firefox, however, has maintained a more permissive stance, allowing uBlock Origin to continue functioning without major changes.
“The extension remains fully supported on Firefox, and there are no plans to discontinue it on this platform.”

The policies of these browsers regarding content modification and extension security are still evolving, and there has been no official statement regarding support changes.
Additionally, it remains uncertain whether Firefox’s support will persist long-term if other browsers adopt similar policies or if the extension’s developer plans to adapt to new platform requirements.
