AFAIK unconfirmed parent mean that you spent or sent the coin from which the transaction which it came from is still unconfirmed (the incoming transaction in your wallet. Your outgoing transaction will be confirmed next once that incoming transaction is confirmed. Still it depends on the fee on how long it will take to be confirmed.

Like the other member posting along with you I have no direct experience with a Ledger.  I do with a Trezor, which of course is another hardware wallet.  Using this model you can easily work with a "phone" and a Trezor using MyCellium.  Very fast and safe as can be.  Then you can still use the Trezor with Electrum on your home computer.  Versatile and safe as can be.  It would surprise me some if Ledger did not have the same option.  In both applications the private key is never revealed to a computer or phone, not ever.

CoolWallet has some interesting features but is priced at $119. You can get a Trezor for $99 or a Ledger Nano S for $65. The CoolWallet devs need to make a case, explain why someone in the market should pay more for a CoolWallet. Also the next gen hardware wallets like Trezor 2 and Ledger Blue will be coming out late this year or first quarter 2017. People who buy hardware wallets tend to buy from companies who have been around a few years with proven products.

CoolWallet is by far the most convenient and secure hardware wallet.
It is now available on: https://coolbitx.com/coolwallet/product.html

According to that website my mixer service is a scam because i once created a wordpress page?

The wordpress page is just a post i made to describe how to access Bitcoin Blender over Tor, so if people google for Bitcoin Blender they will hopefully see this thread here on bitcointalk or that wordpress page and find their way to the correct site instead of a phishing site.

Also read up on the true hardware wallets that work with Mycelium. I like my Trezor, for example, but there are at least two more hardware wallet types that work with Mycelium and that can keep even large bitcoin amounts safe while still allowing transactions with them.

The gadget is using Internet Explorer in the background, with all your current IE proxy and other settings, so it should work for any URL that is not blocked by your company firewall. Depending on exchange, this is usually either http (port 80) or https (port 443) GET connection, which are usually enabled by default unless specifically blocked by your network administrator. If you can access URL in browser, gadget will also be able to access it.

And you're correct, by default gadget updates every 10 minutes (mining defaults) which is enough for non-traders, and if you choose trading setup it will update once every minute, which can be changed to less. Exchanges usually have minimum period between requests that you should respect while setting up update frequency.

Just add a feature request to /electrum github, i dont have a github account, so any of you guys should do it please.

Hmmmm, strange. It should work for Chrome as well. I'll look into it.

EDIT: It seems to be a Chrome issue: https://bugs.chromium.org/p/chromium/issues/detail?id=560809 I'll see if I can work around it or not. Sorry for the inconvenience caused.

Nice! Thanks!!
