Steps to reproduce

  1. install the attached extension
  2. check the ‘allow InPrivate browsing’ option
  3. open InPrivate window
  4. a new tab with title “CoolCmd” will open and after 5 seconds the second tab will open

***** Expected *****

The console of first tab should contain the message with text “!!!”
The console of background page should contain 2 messages with text “!!!”

***** Actual *****

All 3 consoles are empty because sendMessage() does not send anything to other private tabs. My extension (and I’m sure many others) can not work InPrivate mode because of this bug.

Chrome and Firefox working as expected.
