Actually, I do, I have a fair bit of stuff added there by Spybot and a decent amount added by uBlock.
So it looks like you're aware of that, so an upcoming update might fix it? I will try to do the same thing with a temporarily defaulted hosts file and see what happens. Thanks!
EDIT: Yep, it made unloading Cypher/Strobe much quicker. It still wasn't instantaneous (as it is with like 99% other plugins that I have), it took like 4-5 seconds, but no hang. If removal time can be improved, that'd definitely be nice
