Firefox is now the last major browser that still supports uBlock Origin
Firefox now stands as the last major browser to fully support uBlock Origin, as Chromium-based browsers migrate to the more restrictive Manifest V3 API. This move by Google, which effectively cripples robust ad-blocking, has ignited a fiery debate on HN about browser monopolies, user freedom, and the true motivations behind these technical shifts. Many see Firefox as the internet's last hope against an ad-saturated, Google-controlled web.
The Lowdown
As the web's landscape continues to shift under the influence of Chromium, Firefox has carved out a unique, and increasingly vital, niche: it remains the sole major browser to fully support uBlock Origin. This stance directly contrasts with the widespread adoption of Manifest V3 by other browsers, a change initiated by Google that significantly curtails the power of ad-blocking extensions.
- The Chromium Shift: Most web browsers today, including Chrome, Edge, Opera, Brave, and Vivaldi, are built on the Chromium engine. Google's transition from Manifest V2 to Manifest V3 impacts these browsers, forcing extensions to adhere to a new, more restrictive API.
- Ad-Blocking Limitations: Manifest V3 limits the capabilities of ad blockers, making it harder for extensions to identify and block ads comprehensively. This often results in 'Lite' versions of ad blockers, such as uBlock Origin Lite, which are less effective.
- Firefox's Independent Path: Firefox, notably not based on Chromium, has committed to maintaining support for the more powerful Manifest V2 architecture, thereby preserving full functionality for uBlock Origin.
- Other Non-Chromium Browsers: While Safari and DuckDuckGo are also non-Chromium, they do not offer the same level of uBlock Origin support as Firefox, leaving Mozilla's browser in a unique position.
This development positions Firefox as a critical alternative for users who prioritize comprehensive ad-blocking and view Google's Manifest V3 as a step towards greater corporate control over the browsing experience.
The Gossip
Manifest Misgivings and Monopoly Musings
Many commentators express strong disapproval of Google's Manifest V3, viewing it as a deliberate tactic to weaken ad blockers and further consolidate control over the web. They argue that Google, an advertising giant, has a conflict of interest in developing browser APIs that restrict ad-blocking. While some acknowledge Google's stated security and performance benefits for V3, others dismiss them as pretexts for commercial gain, lamenting the loss of extension freedom and the boiling frog analogy for users. There's a palpable sense that this change erodes the 'openness' extensions once promised.
Firefox's Fighting Chance and Flaws
The discussion extensively covers Firefox's role as the last bastion for full uBlock Origin support. Many users laud Firefox for this stance, seeing it as a potential catalyst for regaining market share and a champion of user-centric browsing. However, opinions are divided on Firefox's overall viability; some passionately defend it as a perfectly functional daily driver, while others are critical, citing perceived performance issues, past policy changes (like data selling), or Mozilla's 'AI efforts' as misaligned priorities. The debate also touches on Firefox's market share, questioning whether it truly counts as a 'major' browser, despite its significant presence in certain regions and among desktop users.
Alternative Avenues for Ad-Aversion
Users propose and discuss various alternatives to Firefox for ad blocking. Many point to Brave Browser, citing its built-in ad blocker and, in some cases, an opt-out for Manifest V2. Vivaldi is also mentioned for its continued Manifest V2 support (at least temporarily) and the ability to load uBlock Origin as an unpacked extension. There's skepticism about the efficacy of 'Lite' versions of uBlock Origin under Manifest V3, with some users noticing no difference while others highlight technical reasons why the full version is superior. The conversation also drifts into custom extensions and the contentious involvement of figures like Peter Thiel in some browser projects, raising privacy concerns.
Vetting Vigilance and Security Scrutiny
A notable theme highlights Firefox's rigorous vetting process for extensions, particularly uBlock Origin. Commentators praise Firefox for actively reviewing uBlock's code for every update, going beyond automated checks for 'recommended extensions' to ensure security, functionality, and user experience. This commitment to security and user trust is seen as a significant advantage over other browsers, where the potential for malicious extensions or privacy breaches is a concern. Some suggest that Firefox could enhance this by integrating ad-blocking functionality directly into the browser, but this is met with the counter-argument that Google's financial influence on Mozilla makes such a move unlikely.
