@qpayct Can confirm your issue about the CSP. When you remove it Opera states "Manifest format version is not supported.".

@gmiazga @qpayct @namero999 Currently the Opera Add-ons Store doesn't support manifest v3 extension packages. When can we expect the store to support them?

@gmiazga Thanks a lot for the explanations. Is there any reason why the non-blocking webRequest API and/or blocking webRequest API won't be supported in v3 by Opera?

Opera's addons.opera.com doesn't seem to accept M3 extension updates, though.

I get the feeling, Opera is kind of slightly abandoning its own extension repository, by the way. Is it right, that users as well as developers should concentrate on Chrome's addon store instead?

@gmiazga By now we as developers and users really need to know when Opera will support Manifest v3 on the Opera Store. OR, if the Opera Store will be phased out and we need to migrate people to the Chrome Web Store.

@carlosjeurissen at the moment we do not have plans for closing our store. Will try to get some information about plans for allowing v3 in our store.

@carlosjeurissen I got information that support for v3 in addons.opera.com has been scheduled for development. No ETA on it yet, so I will try to get this post update.

@vjik7 I got information that upload od manifest v3 extensions should be possible within a week. Migration of old extensions and deprecation of v2 will be done as separate tasks later.

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?
