Chrome extension CopyFish hijacked: remove now!
https://www.ghacks.net/2017/07/31/chrome-extension-copyfish-hijacked-remove-now/
The makers of the popular Chrome and Firefox extension Copyfish announced yesterday that the Chrome version of the extension was hijacked.
...
Chrome users who have Copyfish installed right now are advised to remove the browser extension from the web browser until the situation is resolved.
...
The Firefox extension Copyfish is not affected, and there are several reasons for that. The most obvious one is that the attackers phished the Google account password and not necessarily the Mozilla account password. While it may be identical, it does not have to be.
