> mail.tabs.loadInBackground defines how a new tab will load. Double clicking or middle clicking a message would both make the message load on the background if mail.tabs.loadInBackground is true. 
> bug 1888872

Middle-click previously just failed to work - but now it is working perfectly ok.

But double click to open in anew tab - opened in new tab but no focus.
Why the default  is still set on 'True' which in previous versions was irrelevant because a double click to open in a new tab always worked no matter what setting was set as default. Email always opened with focus in tab. However, now that means by default will suddenly work correctly and people will find they do not have focus.
Please set the default to 'False' so that the Support Forum is not inundated with people asking why is Thunderbird not opening with focus when you double click.

OR have I misunderstood and is this an update which is not yet been uploaded 125.0b2 ?
