This question was originally Does Firefox in VM have a common enough fingerprint so I don't need tor browser? in Tor community.

I want to know about what a web browser's fingerprint like in a VM, if VM runs a common OS and have default system settings. Can VM be configured to not have any of host machine's fingerprint?

(Here I just want to ask about fingerprint, ignoring IP addresses, web scripts and tracking cookies)

Here the VM software we discuss would better be FOSS, like Virtualbox or qemu.

That question could be on not just web browser, but also other kind of softwares.


No hardware based virtualization as implemented in practically all relevant virtualization systems fully hides the details of the underlying hardware. If you want to fully hide the details you would need to have full software based virtualization of the processor too, i.e. like emulating an ARM processor even if using an x86 one. Qemu can do such things but it will be terrible slow.
