I like both these experiments - especially Pulse for when my friends complain that Firefox feels slower on a particular website.
If someone from the Test Pilot team is on this thread, can you let us know if "Suspend Tabs" is being considered for a Test Pilot experiment at all? SnoozeTabs plus SuspendTabs along with e10S would make for a great trifecta of features for my Firefox usage profile.
Thanks for the great work on these and the other experiments.
