Opera Reaffirms MV2 Extension Support as Chrome Removes Manifest V2 in Version 151

Summary
Opera said its “position is unchanged” and users can still run installed MV2 extensions for now, pushing back on reports that it was preparing to abandon Manifest V2.
September 2025 guidance from Opera says it is actively trying to preserve MV2 “for as long as it’s technically reasonable,” even as it shifts toward an MV3-only extension store.
Chrome is moving the other way: Chromium 150 already dropped one MV2 control option, and version 151 is set to remove more flags and legacy workarounds that had kept extensions like uBlock Origin alive.
Opera also said it no longer allows new MV2 uploads and will phase out many older, less-used MV2 add-ons, signaling that continued support is temporary even if popular extensions may last longer.
