User reviews
This add-on works (as my memory drops dramatically in a matter of minutes after install with over 100 tabs open) but nowhere can I find the options to set suspend time, whitelist urls, ignore/disable items (as shown in your screenshot). How about some basic information on where this can be found & what to expect on install?? I've uninstalled/reinstalled/rebooted to no avail. Moving on to another add-on
