1454150 - Setting the browserAction title for the first tab in a new window during the onCreated event does not work

Status: RESOLVED INVALID

(WebExtensions :: Untriaged, enhancement)

Description

[Dave Townsend [:mossop] (PTO until July 20)]

When you open a new window you get the following events:

browser.tabs.onCreated
browser.windows.onCreated

Attempting to set a custom browserAction title for the first tab in the new window from either of those events appears to fail. I tested with the following code:

browser.tabs.onCreated.addListener(tab => {
  browser.browserAction.setTitle({
    tabId: tab.id,
    title: "Success",
  });
});

Opening a new window I'd expect the browserAction to have the title "Success" for the first tab. It actually ends up with the default title. Subsequent tabs are fine.

This is the expected behavior. Tab-specific values are cleared as soon as the tab navigates, and the tab pretty much always navigates shortly after the onCreated event.

Hrmm what an awful API. Can we get some docs on that, what it says right now it "Automatically resets when the tab is closed"
