I don't feel completely comfortable running a client that's got open access to the net when I cannot be sure of exactly what information that client is sending. And I noticed the there's a new firefox 7 & chrome addon that you can keep your wallet in.
But I am wondering how does it do this?
1. Does it run a btc client program on my computer (in the background)?
or 2. does it use the blockexplore service to run the client and just keep my wallet up to date for me? Thus using little to no resources on my computer... etc.
3. What exactly does this app do?
Anyhow, below is the info that's listed on the firefox site about the addon. Please tell me your thoughts on this. Thanks!
