MemShrink (njn)

• Firefox's start-up memory consumption, as measured by AWSY, has almost doubled in the past two years. While this isn't reason to panic, it is worth investigation. This dev-platform thread discusses the contribution of new system compartments, and whether they can be avoided.

Roundtable
