Details

While we are able to detect low-memory scenarios we currently respond to them only by purging caches, trimming buffers and running the garbage collector. From the telemetry data we've gathered about OOM crashes this usually helps in keeping Firefox alive for longer when it enters a low-memory state but is unable to save it from crashing unless the user manually closes some tabs.

Now that tabs.discard is supported we should be able to automatically unload tabs in low-memory scenarios. This should greatly increases the chances of avoiding an OOM crash.
