uBlock. A lightweight ad-blocker that is faster than the competition. If you use Ad Block or Ad Block Plus, you can see that it delays the loading of websites quite significantly. I use Ad Muncher as well, which is a host-based solution that you have to install as a separate application, not as an extension. Ghostery. Blocks social media and advertising trackers.
HTTPS Everywhere. In light of all the hacking going on, it's a good idea to enhance your security. This extension redirects you to the encrypted version of all websites.
ScriptBlock. Do you hate the stupid ads that pop up when you're viewing a website? ScriptBlock controls the scripting language that makes it all possible. It's easier to use than the other script blocking extensions. When you access a domain for the first time, you will have to allow that domain. Then you should be okay.
I haven't blogged in a while but I had a bunch of new Chrome extensions I wanted to share.
1. Crypt-Up. Emails are very insecure; they bounce around weird servers that you cannot control. And encryption has been very annoying. Crypt-Up is an extension that beautifully implements PGP encryption for Gmail. (Right now, it's only for Chrome but mobile apps are being planned.) Under the PGP encryption scheme, every user has a private key and a public key. The private key is kept secret, and the public key has to be shared. To send an encrypted email, the sender uses the recipient's public key to scrambled the email. The recipient's private key is the only (known) way to unscramble it. Crypt-Up does a good job of keeping track of private and public keys, and sending emails. You can export your private key to use other PGP products and import your friend's public keys so you can send them emails even if they don't use Crypt-Up. Try it out!
