To help the team around the Memshrink project Mozilla QA Automation Services has released Mozmill Crowd 0.1.4. In this version the only changes which affect the extension itself are additions for the Endurance test-run, which allow users to specify the number of entities and if Firefox has to be restarted in-between each test.
We also have moved our Mozmill environments for all platforms from my own Mozilla people account to a new secure location on mozqa.com. In the future please always use this new location to grab the latest version of the environment.
For more information please see the tracking bug for Mozmill Crowd 0.1.4.
