let me know if this helps your problem

If by popups you mean opening browser tabs or windows, it might be something along these: * [[How to set the home page]] * [[An extension changed my New Tab page or home page]] * [[Wrong home page opens when I start Firefox - How to fix]] (it can be caused by a rogue extension or system malware that's resetting that for you constantly) If by popups you mean system notifications showing up in the corner, see: * [[Web Push notifications in Firefox]] incl. steps how to revoke any site.
