Package: firefox
Version: 55.0-2
Severity: wishlist
I've noticed that firefox 55.0-2 takes much more memory on disk than
firefox 54.0-2 (155107 KB vs 108884 KB). Looking at the deb files,
this partly comes from the fact that the omni.ja files were compressed
in FF 54, but this is no longer the case in FF 55 (a total difference
of 27 MB). This is probably due to the upstream change discussed in
https://bugzilla.mozilla.org/show_bug.cgi?id=1362377
(RESOLVED FIXED in Firefox 55), and it appears that this wasn't done
on purpose in the Debian build (nothing in the changelog.Debian file).
It seems that there were two reasons for this change upstream:
1. Reduce the download size for partial updates.
2. Possibly reduce the startup time.
However, for Debian, (1) doesn't apply since updates are provided
only by its package system.
Concerning (2), this is unclear, even for upstream. See in particular
Comment 3:
https://bugzilla.mozilla.org/show_bug.cgi?id=1362377#c3
Also, the telemetry tests were done on MS Windows (yes, for their
global choices, upstream favors MS Windows).
So, unless it is shown that there is a clear improvement for the
(cold and/or warm) startup time, it may be better to revert this
change for Debian, i.e. re-enable omni.ja compression.
