Best script blockers?

[Dusty Chalk]

I reinstalled Chrome (because it was acting up, and nothing short of deleting it entirely was making it better), and can't seem to find my script blocker.  I thought it was called NoScript...tried uMatrix, but that doesn't seem to remember my whitelist.  Am I using it wrong?  Is there a better one?  Where is noScript?  Any better recommendations?  I should also probably add something similar to my Firefox -- any recommendations?  

I'm still using The Great Suspender in Chrome -- that's still a godsend.  Anything similar in Firefox?
