Detects cross frame references that prevent iFrames from being garbage collected
- Click "Reload the page, leak more memory" to refresh the inner iFrame
- Notice the increase in memory usage, this is because the inner iFrames are still referenced
- Click "run iFrame memory leak detector"
- View dev tools console to see output
Only events/variables on the immediate window are checked, this means any objects within objects could still have pointers to frames
