From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

TOR browser User Agent in Linux increases fingerprinting (programming.dev)

I usually use Tor Browser to scan files online for viruses, which I then send to Windows users (I use Linux) if they are clean.

Lately, I've noticed that the User Agent in TOR is showing up as Linux, when it used to show up as Windows.

Is this a problem with my system or a change made by the TOR team? The fact that Linux has far fewer users increases fingerprinting.

Like with image handling or whatever.

I'd expect TOR browser to mitigate this. Canvas2D is disabled for instance and system fonts aren't exposed.

Most other things could be mitigated by making every platform use the same code paths for e.g. font rendering. It should be pretty damn hard to determine which OS it is when the userspace is the same. I don't know whether TOR browser currently does this though.
