Sunny, are you the developer of the "Free Memory" add-on? The add-on seems to have a performance problem with multiprocess Firefox (e10s). If you have any questions about e10s support, just drop by the #e10s IRC channel on irc.mozilla.org or ask Jim Mathies on this bug. MDN also has a good introduction:

The "Free Memory might be making Nightly run slowly" status bar warning means that Firefox thinks the add-on is spending too much time running script:

Given the comment about Free Memory 2.0, I'm going to mark this wontfix.
