edit: Sadly it seems the person behind this now attempting to steal peoples coins and has updated what was a previously safe extension with malicious code intent on redirecting coins to an address of theirs when withdrawals are made on exchanges
If you use any extensions in your browser, you're vulnerable to updates which happen automatically without your knowing.
This means you can be using it for weeks/months until the bad author updates the addon/extension with malicious code. It appears the author made an update today to steal Ð among other digital currencies

The extension is Cryptsy Dogecoin (DOGE) Live Ticker
There is likely similar tickers for other currencies.

Be careful of what you install on your devices you use to access your wallets.
Stay safe fellow shibes.
