Dear friends of freedom and privacy,
I would like to share with you some of my recent findings about popular FOSS browsers which (imo) disrespect user privacy.
I am sharing with you direct links to the reported issues:
IceCat: I have reported this directly to GNU and FSF, so there is no link but I will try to attach it here icecat-privacy.txt
I am using openSUSE Leap 42.3. I still haven't tried PureOS or PureBrowser but I thought I would share these with you as you might want to check more in-depth the validity of my concern and hopefully prevent code disrespecting privacy to propagate in your systems.
FWIW here is also a discussion I started in the openSUSE forums about all this (others seem to confirm what I notice through testing via wireshark):
