Bug: WindowsActivityTracker does not seem to track when using Full-Screen Mode in Firefox on macOS

[Xayreen]

In my case, the WindowsActivityTracker did not recognize any window activity while navigating and switching between tabs during the use of Full-Screen mode using Firefox on macOS. It constantly kept track of the last opened application on macOS and did not update any of the attributes such as windowTitle, process and activity, after switching to Full-Screen in Firefox.

thank you @Xayreen for reporting this bug. And did I understand correctly, that checking the active-win-library did not result in a similar/related issue?
