Comment 18 for bug 246843

Our crash reporting system works the opposite way, sort of. We simply generate a minidump on the client side that includes the raw stack data and registers, and upload it to our crash report server, which has debug symbols that are uploaded from when we build the binaries.

All we really need to get useful crash reports from your users is:
1) You run the "make buildsymbols" in the Firefox (or xulrunner) objdir before packaging the build, and upload the symbols to our symbol server (we have "make uploadsymbols" for that, as well)
2) You start building without --disable-crashreporter, which will let your builds use our existing crash reporting mechanism to submit to our crash reporting server.
