Same for other reporter that can repro, can you check in [latest Nightly](https://www.mozilla.org/en-US/firefox/channel/desktop/#nightly) ? The tarball can be decompressed, ran directly and deleted. By default, this happens on non-debian-based system I think, although you can configure a debian-based system to repro.
