@willdurand I've verified add-on uploads on stage - ranging from simple to complex extensions (I've used some high profile extensions as well) to see if there are any issues with the latest linter release.

I didn't know what syntax should be used to tests all the individual changes mentioned in your issue comment. The addition of action as an alias for browser_action was pretty straightforward, but the others not so much:

• replacing browser_action with action => MV3 doesn't trigger errors or warnings during validation; MV2 triggers the following warning:
