fixed potential infinite loop in `popupRemover` function..

[qw87rt]

The popupRemover function runs every second & can cause performance issues if the process is slow and if therr are frequent popups. //can also be applied to removeAds function cuz not clearing them can lead to performance issues if many intervals are running simultaneously.

1. added flag variable isPopupBeingProcessed
2. At the start of the interval function, we check if isPopupBeingProcessed is true
3. set isPopupBeingProcessed to true to indicate that a popup is being processed.
4. After the popup removal process is complete, we reset isPopupBeingProcessed to false.

this should help mitigate potential performance issues.
