Konqueror is My Goto as It by defualt supports plain FTP. In My Gaming VM I use Waterfox and currently testing duckduckgo, though like most privacy forks, with Waterfox you run the risk of being behind on security patches, Its In a VM for me so i honestly cant be arsed.
Chrome is Still sadly the fastest if you subtract the spyware from the background. Degoogled Chromium is only slightly slower though. I don't notice speed difference really. I Have tried Gnome Browser and thats Extremely slow in comparison to Firefox.
