As the summary says, there is a bug in about:debugging regarding tabs recently created in other windows than the one containing the about:debugging tab. [Steps to reproduce]: 1. Launch Firefox 2. Open about:debugging 3. Go in the tabs section 4. Open another window 5. Open a new tab in that new window (the first tab opened by default isn't concerned by the bug) 5. Check in about:debugging (in the other window) that this new tab has been detected 6. Type an URL in that new tab and press enter 7. Once the website has loaded, check again about:debugging [Expected result]: - This new tab summary (favicon and title) should have been updated [Actual result]: - The new tab is still shown as a basic "New tab", and its information is only refreshed once you reload the about:debugging tabs section (or force it to reload with another action) I hope this makes sense!
