Is there a better way to report the bug than just use the built-in crash reporter? I still get super sporadic crashes, I think it has to do with having too many tabs loaded.
Yes, if you follow one of the links from about:crashes, you can see the crash report. If there's already a bug on file for it, click on over to bugzilla.mozilla.org and see if you may be able to help out there. If there isn't already a bug active for your specific crash signature, you can try filing one and explain what you think may have caused the crash. Specific steps to reproduce a crash are especially helpful!
Another interesting thing you can do: click through from about:crashes to your crash report. Then click the "more reports" link. You can see if your crash signature is rare or if you have one of the currently "popular" ones. If a lot of other people are crashing with that same signature, there is probably a bug and developers are probably discussing it. Again the most useful thing you can do is figuring out how to make that crash happen consistently and adding steps to reproduce it to its bug.
