Review for EMail Address Crawler by Stiefel_Riehmenbill
Rated 5 out of 5 stars
This Add-On is outrages!!!! Saves you a lot of time.
for those of you who struggle in compability with the recent firefox.
Just get a stand alone old version of TB 3.1 and do your job there. Saves you a lot of time. Then export the List and import in the newest Version of TB.
