Rated 4 out of 5 stars

Memory Fox version 2.4 - In Mode 1 (Memory Fox NOT in system tray) afom.exe does not exit properly when Firefox is closed, or rather it exits randomly (most of the time it sticks in RAM). This, here, since versions after 1.4.9
Otherwise, the best memory enhancer for Firefox, works beautifully.

This review is for a previous version of the add-on (2.4).  This user has other reviews of this add-on.
