Memshrink [4th Tuesday of Month]

Bill McCloskey landed zones, which wins back a lot of the overhead introduced by compartment-per-global. It saves about 6 MiB (~10%) on start-up on desktop, and more with heavier usage. User comments:

• "I have a fair amount of bugzilla tabs pinned and use bugzillaJS, and zones landing caused my profile’s memory at startup to drop from ~650 to ~550 MiB".

• "This has reduced the memory usage of Ad Block Plus quite a lot... about 40-50 MB, with 10 tabs loaded with misc websites."

MemShrink reports: week 89--90, week 91--92.
