Module storage: set stricter storage quotas on Firefox

The 100 kB limit is being effectively circumvented by the fact that
heavy-hitters like VisualEditor are now split up into a greater number
of smaller modules. We can improve matters further by making the per-module
size limit smaller on Firefox, where the quota is especially tight due to
<https://bugzilla.mozilla.org/show_bug.cgi?id=1064466>.
