Bug 1892449 - Set network.http.digest_auth_cnonce_length to 16, a=dmeehan
Apparently, setting this value to 64 breaks some sites. We should use the same length as Chrome.

Bug 1875248 - Check for network error preventing ExternalHelperAppService before DONT_RETARGET, r=smaug
This reverts the change from 30cde47f9364e5c7da78fd08fa8ab21737d22399,
and instead re-orders the NS_ERROR_FILE_NOT_FOUND check before
DONT_RETARGET.
Testing suggests that a-download-click-404.html behaviour isn't
impacted, and this improves the handling of this edge-case when doing
process switching.
