It does send a user agent by default.

I somewhat regularly use Firefox from within the WSL. It's a privacy by obscurity thing for me though.

Doesn't that give you an amazingly unique fingerprint?

Seems so. But I meant more privacy on a local machine basis. That is, someone would really need to dig through the filesystem to find browsing information, rather than just looking at the standard locations.

I recognize it's a weak privacy measure, but in my situation it gives me a mostly private browser on a shared user account.

OK. This sounds like a perfect use for either private browsing mode or another profile with history etc set to false though.

Private browsing wouldn't save any browsing information, which is something I want. Also, using another profile would reveal that the profile exists in the first place. Using the WSL is much more hidden.
