SIGSEGV on particular website with developer tools open

System: linux 64bit (arch linux), gnome3, Tor browser 6.0

Actions to reproduce:

  1. Open F12 tools (Network tab if it matters)
  2. Go to https://archive.org/details/a2_Zork_I_The_Great_Underground_Empire_1980_Infocom
  3. Click on the play button.
  4. After some downloads, the browser crashes.

I've tested this with both the security slider on low as on medium-high and that changes nothing. I went ahead and downloaded the debug systems and got a backtrace in gdb, which I'll include.

If there is anything else that I can help with, do let me know!
