This link appears to reliably freeze Tor Browser 6.5.2:

After about 3-4 seconds, the whole browser just seizes up, and I need to kill -9 it. Tested in a freshly created Fedora 24 Qubes VM. Alex tested it on MacOS and had the same result.

This does not appear to happen in High Security mode in my macOS 10.12.5 VM, so maybe it's JavaScript related (or some other resource we disable in high security mode).

This happens when I 'allow all' JavaScript, but doesn't happen when I only allow fonts, and doesn't happen when I only allow JS from It appears to be some ad/tracker JS.
