In the absence of anything more interesting to write about, here are some Firefox extensions that I've recently installed and found useful or interesting.

In the absence of anything more interesting to write about, here are some Firefox extensions that I've recently installed and found useful or interesting:

1. Effortless Good - automatically adds an affiliate tag for products bought at Amazon, with the income donated to 4 charities. Doesn't overwrite normal affiliate links. Means you can do good with minimal effort.
2. FireGPG - integrates GnuPG with Firefox, and in particular Gmail. You can encrypt, decrypt and sign the contents of a text box or emails. Requires GnuPG.
3. ForceHTTPS - ensures that you're using the encrypted (HTTPS) version of popular web sites like Gmail and PayPal where you share personal information.
4. firefox-mac-pdf - allows PDF files to be viewed from within Firefox on a Mac, rather than in Preview. Mac-only.
5. YouTube Comment Snob - hides idiotic comments on YouTube videos.
