devtools-panels example broken with manifest v3 #562
Description
What information was incorrect, unhelpful, or incomplete?
The README says:
Inject content script: this sends a message to the extension's background script, asking it to inject a given content script in the active page.
The background script uses browser.tabs.executeScript to do this, but executeScript is undefined with manifest v3.
Flipping the manifest version back to 2 makes it work, but I don't think new extensions that use manifest v2 are accepted any more.
