"And who'd have thought that some vendors aren't even interested in fixing "non-security" crashes" That doesn't surprise me too much -- it comes down to prioritization, and often the crashes a fuzzer finds will be weird corner cases that don't happen in the 'real world' unless somebody is deliberately exploiting them. Since 'browser crashes safely' isn't a very interesting outcome for the deliberate attacker or a major issue for the user, it seems reasonable to me that a vendor might prefer to prioritize fixing other crasher bugs that telemetry says users are actually hitting, or fixing bad UI that annoys users, or any of the other thousands of issues in their issue tracker. No software is bug free and no dev team has unlimited resource, so any decision to fix a bug is implicitly a decision not to fix some other bug. "We found this with a fuzzer" isn't an automatic ticket to the front of the queue.
