Firefox continues Manifest V2 support as Chrome disables MV2 ad-blockers 🔗

Mozilla Firefox has committed to continuing support for Manifest V2 extensions, allowing users to retain their preferred add-ons, even as Google Chrome phases out support for them. Manifest V3, designed for enhanced security, imposes restrictions that can hinder the effectiveness of certain add-ons, particularly ad-blockers. While many browsers, including Firefox, have adopted Manifest V3, they have made adjustments to maintain user flexibility. Firefox's decision to keep supporting Manifest V2 aligns with its principle of empowering users to shape their internet experiences, despite potential plans for deprecation previously mentioned.
- Firefox will support both Manifest V2 and V3, giving users more extension options.
- Chrome is disabling Manifest V2 ad-blockers, affecting user choices.
- Mozilla believes in allowing users to customize their internet experience based on its manifesto principles.
