From what I read the exploit tries really hard not to crash anything. It seems pretty confirmed that it only works on Windows and outdated versions of Tor Browser, and the most recent obfsproxy browser unfortunately. I heard there was a second exploit that replaced the first one that used some image tag vulnerability, so that one might work without javascript being enabled but it still only will work against Windows I think. I have not heard much about the second exploit only the first one, but someone in an IRC analyzing this situation found a second exploit as well according to them.
