Only extension i tested so far that really disables this annoying tab focus stalking. I expect this infantilism to be used on much more websites... good we have a guard here. Check the extension i.e. on: https://www.daftlogic.com/sandbox-detect-when-page-is-not-visible-using-javascript.htm Edit: Unfortunately there is a huge CPU usage on browser restart which does not end... only when i disable this extension. Re-enable and surf triggers again the CPU massive usage. Too bad.
