But as an experienced Chrome user, you must now answer: I do not know. The above answer is a good start. Along with explaining your heuristics, how would you try to crash Chrome:

• Search for Chromium project issues on its Github project page (oh, there is no such page)
• Investigate cmd line options and what they do
• Try to crash it by running Javascript code

All these heuristics could reveal your specialty. Your specialty should be mastery in resolving never seen issues on Chrome. How to become a generalist in Chrome specialty?

One option could be to join the Chromium project and check testing documentation. There is a lot of information to start learning about Chrome internals.

Conclusion

If you are a specialist, you need to be a generalist in that specialty.
