Comment (by cypherpunks):

 I have 2 TBBs. Both are upgraded from old versions, time to time.
 5.x -> 6.x -> 7.5

 And both keep webext add-ons and they are working just fine.
 When I downloaded fresh TBB, webext is not working at all.

 I think this issue is happning on 7.0/7.5 _new_ users.
 Old users like me shouldn't have this issue.

 And,

 > [System+Principal]

 is NOT exist in my whitelist (Noscript options - Whitelist).
 Both TBBs don't have it, but able to use webexts. I wonder why.
