After some research using Google, which resulted in nothing, I decided to look into this problem a little deeper. I started by looking through the logs which yielded nothing either. I removed Filezilla with and without purge(purge should delete all of the files used by Filezilla) this also didn’t fix my problem.
Next I deleted the ~/.filezilla folder, a hidden folder in my home directory also know as ~, this fixed the problem. If you would like to keep the folder then just rename the folder:
mv ~/.filezilla ~/filezilla_OLD
This fixed the problems with Filezilla crashing for me. If this worked for you then please leave a comment below. If it didn’t work please leave a comment as well so I can help you fix it.
