Rated 5 out of 5 stars
@jrod : "Browser only" as it mentions, handles Firefox's RAM only, whilst "All processes" manages all processes you can find in your "Task Manager".
Personally I prefer this version 7.4 to the 7.5.3 which is available on the author's site. Here MF 7.4 with "All Processes" works brilliantly, close the browser and "afom.exe" remains working in the background, and doing a hell of a great job.
Don't forget, if you opt for "All Processes" that MF has in iys options a blacklist available in case should some apps/processes should rather not be managed (none here at this time)
