1488404 - Consider including heap data in minidump for beta release channel

Status: NEW

(Toolkit :: Crash Reporting, enhancement)

Description

[Jean-Yves Avenard [:jya]]

When crashing, the minidump doesn't include any heap data for release and beta, only for nightly

This was likely okay when the aurora channel existed, giving us broader coverage and data to help understand a crash.

With the nightly population being very small, it is often not possible to find a particular crash signature for the nightly channel, making crash investigation difficult.

It would be useful to consider including heap regions of the crash for the beta channel, or at least early beta versions.

We discussed this on IRC the other day because jya was looking at a crash where heap memory would have been useful, but he could only find crashes with that signature from beta and release. With aurora gone it probably does make sense to make this `EARLY_BETA_OR_EARLIER` to get more useful crash data from betas.

We still have Developer Edition (what used to be aurora) as a rebuild of beta, where we could set this even if we don't do it on beta (there are plans to make DevEdition a repack rather than a rebuild, though, so I don't know for how long that would work).
