@2-X you haven't made any changes that migrate this to Manifest v3. That would start with a change to the manifest.json file line "manifest_version": 2. These examples are intended for firefox, hence they use the browser namespace. Were you running this example in Chrome?

@rebloor thanks for the reply! yes i was running it in chrome, i see that browser is the firefox version of chrome API. something like this PR should instead be part of a larger refactor to make them all work on both chrome and firefox, if desired, so i closed this PR 👍🏼
