Hi, you could build in some logic into your object to check for the existence of this 'popup' in FF. If it happens all the time it is easier but if that is the case then maybe there is a more fundamental problem with the site which needs further investigation.
What you can do is to perform a 'check exists' on an element on the site with a timeout. If that check does timeout then you can follow a path to check for this popup. If that also fails then you know the popup doesn't exist at this time and the issue is something else. If it does exist you can then deal with it in whatever way you decide.
