What happened
Microsoft Edge is ending support for Manifest V2 (MV2) extensions, disabling older ad blockers like uBlock Origin starting this month. Only 58 extensions with meaningful usage still rely on MV2, and just 3 lack MV3 equivalents. Consumer transition completes by end of 2026, with enterprise following in early 2027.
Why it matters
If you or your team relies on uBlock Origin in Edge, it will be gradually turned off—switch to uBlock Origin Lite or another MV3-compatible blocker now, or move to Firefox or Opera if you need full MV2 capabilities.
Discussion angle
What actually breaks when moving from uBlock Origin to uBlock Origin Lite under MV3, and whether Firefox or Opera is a realistic long-term holdout for power users.
