I am having problems accessing Dropbox and have pinpointed the problem (using safe mode) as being Noscript. Until a couple of weeks ago I would get the Noscript warning box up when I tried to sign into Dropbox, warning me of cross-scripting attack etc. I thought I had whitelisted Dropbox but since last week it doesn't let me in at all. Press sign in and it just hangs. Either Noscript has changed (currently 10.2.1) and I haven't noticed something, or I need an alternative to Noscript.
