Sure, but this isn't a _Tor_ issue. It's just about Tor browser, which
is just (heavily) modified Firefox. And although I'm no software expert,
I'm guessing that it's impossible to guarantee what some code will or
won't leave behind when it crashes. Even if you tweaked the browser to
never write temp files to disk, and keep everything in RAM, you couldn't
guarantee that the OS won't write stuff to disk.

That is, unless there _is_ no disk, as in Tails. Even with Whonix,
traces likely remain in the virtual disk. And sure, you can run Whonix
with virtual disks, which don't persist changes. But even then, who's to
say what might get left on the host. I'm less familiar with other
sandboxing options, but I suspect that there are similar issues.
