Some NoScript whitelists may become permanent
I have several Tor Browser profiles and I just noticed that on two of them there are some permanently whitelisted addresses.
One profile had all of these while the other one had just mega.nz's. Seeing it one two separate profiles suggests it wasn't an isolated case. Each profile is a few months old and have been through several Tor Browser updates. Currently on 8.0a1 (win64)
