It took way longer than expected but it's finally here. Changes have been deployed on production and it should be possible to upload extensions using manifest v3.

@gmiazga Thanks for the MV3 timeline!

Is it already clear how Opera will handle browser-specific choices and features?

• How will the sidebar API change in MV3? (See https://github.com/w3c/webextensions/issues/128)

Mozilla Firefox decided to handle MV3 a bit different than Chrome to help developers and users:

• Will the webRequest still be available in MV3 (Unlike in Google Chrome)
• Will Opera keep supporting non-persistent background scripts?

(When) does opera want to stop supporting MV2 extensions on the store and in the browser? Due to all the issues with MV3, can we as developers ask for extended support of MV2 on the Opera Store? Or allow publishing both MV2 and MV3 at the same time for best backward compatibility?

@gmiazga when is the full transition to Manifest V3 planned, and when will it be prohibited to load the extension with Manifest V2?

Or is there no certainty yet about when exactly this will happen, and it is safe to continue loading the extension with Manifest V2?

@alitoolsio I noticed that few developers like SIMKL's Netflix Enhancer have already started updating their browser extension to Manifest V3.

I still kinda use those old browser extension that run on Manifest v2 (which were not updated for ages) but still useful to me - I wonder, what will happen to those apps.

People are reporting mv3 warnings in the extensions panel.

Why is this appearing before Opera gave any statement on their mv3 schedule? What is the timeline?

@carlosjeurissen Probably is Chromium doing it.

@leocg Yes, still would be nice if Opera would hide these warnings for the time being until they have an mv3 schedule.

Any updates on MV2 removal?

@pilis00 Nope, MV2 will continue to live in Opera.

An update from an Opera developer would be a lot better to be heard.

@pilis00 Yes, In Chromium 139, they will make a statement when support is officially cut off.
