It's sad that FileZilla remains so popular long after the creator has chosen to monetize it with adware. I highly recommend any FileZilla user reading this should switch to WinSCP. It's free, open source, and not bundled with any crapware.
Cyberduck[1] was what I moved to after the FileZilla installer on Sourceforge forced me to wipe & reinstall Windows a few years back. It's available for MacOS and Windows, GPL3 licensed[2] and worked great for me at the time. I've since moved to Linux so I haven't been able to play around with any of the newer features/versions but it would be the first thing I tried if I switched back today. Definitely recommend taking a look.
