CCAV doesn't seem to like the new Firefox Quantum in the Sandbox. It blocks everything as supposed to, but when FF is added as an exception or connection is allowed by unchecking those options in Sandbox, all the tabs crash as shown. If attempted it more than 3 times, it results in BSOD with Unexpected Kernel Mode Error
Firefox 56 behaved perfectly and FF Quantum works perfectly in CIS Containment
It's certainly not critical for me . . . . just testing everything
