>>> My Info: Win7_64, Nightly 49, 32bit, ID 20160526082509 STR_1: 0. Open new Firefox window 1. Copy "view-source:https://www.youtube.com/" to clipboard 2. Open new tab in the window from Step 1, press Ctrl+V to paste url to clipboard 3. Press Enter, then immediately press Alt+Tab (and release Alt) to switch to another Firefox window AR: When tab from Step 2 loads, the window from Step 1 becomes focused ER: The browser shouldn't steal focus from another window, because: it knows that I switched between windows AFTER I navigated to that url

I wasn't able to reproduce on the latest Firefox release (50.1.0) on Mac.
