Don't know if it is extension related
But it can also occur when starting PM in Safe Mode
In my case, I use Session Restore, & as it is, about:addons is one of the tabs restored.
Have not looked, tested to see if any "new instance" of Addons Manager always opens as expected (i.e. with no existing Addons Manager window opened already).
