Steps to reproduce:

With WebExtension

  • Register tabs.onUpdated listener
  • Navigate to a website that plays sound, e.g. and click any playlist
  • tabs.onUpdated fires with audible changeInfo
  • Reload the page
  • Start playlist again
  • tabs.onUpdated doesn't fire with audible changeInfo

Without WebExtension

  • Open new tab
  • Navigate to a website that plays sound, e.g. and click any playlist
  • See the loudspeaker appear in the tab bar
  • Reload the page
  • Start playlist again
  • See no loudspeaker appear in the tab bar

Expected behavior:

tabs.onUpdated with audible changeInfo should always fire and the loudspeaker should always appear if there's sound in a tab.

Actual behavior:

tabs.onUpdated doesn't fire with audible changeInfo and the loudspeaker doesn't appear after reloading the page if there's audio in the tab.


Not sure if this is actually a WebExtension bug, since the loudspeaker is also affected.

Tested with Firefox Dev Edition 67.0b15 and Nightly 68.0a1 (2019-05-03) on Linux. And with Nightly 68.0a1 (2019-04-02) on Windows 10.

Works as expected in Firefox 66.0.3.

Component: General → Tabbed Browser
Product: WebExtensions → Firefox

I can reproduce the issue on Nightly68.0a1 windows10.

I managed to reproduce the issue using an older version of Nightly (2019-05-07) on Windows 10 x64.
I retested everything using latest Nightly 69.0a1 and Firefox 68.0b12 on Windows 10 x64, macOS 10.13 and Ubuntu 18.04 x64 and the bug is not reproducing anymore.
