The Firefox Extension Guru (El Guru)

FF Extension Guru

Born and raised in California, relocated to Arizona in the summer (nothing like jumping right in) of 1993. In 1999, I obtained my Bachelor’s in Marketing from Arizona State University. This blog is my way of ‘marketing’ Firefox and Thunderbird. I took the plunge and installed Firefox and Thunderbird on Christmas 2005 and have been using, testing and even crashing it ever since.

When I am not surfing the tech blogs, I spend most of my time tweaking (which includes crashing) Mozilla Firefox & Thunderbird as well testing and reviewing extensions. I’ll even play with beta and released versions of other browsers such as Netscape, Opera and Safari (but not IE7/8/9). I can also be found over at Go Firefox! on DelphiForums (where my nickname originated) or reading various other blogs (see sidebar). In addition, I operate a freelance web design business, AlNetSolutions.US (see in Links of Interest on my main blog page).

What Is Thunderbird?

Thunderbird is a FREE open-source and cross-platform mail client.  It is free, and was created by Mozilla.org, the original creators of the Netscape browser and Firefox.

My mail client seems fine to me.  Why use Thunderbird?

The article, Why you should use Thunderbird, provides many reasons why you should use Thunderbird instead of other mail clients.

What Features Does Thunderbird Offer?

Thunderbird has many built-in features such as:

  • Supports IMAP and POP mail protocols, as well as HTML mail formatting.
  • Can be used with AOL Mail
  • RSS capabilities
  • Junk Mail Filters & Anti-Phishing Protection
  • Advance security features including, S/MIME, digital signing, message encryption, support for certificates and security devices.
  • Automatic Updates
  • Customization with extensions and themes (just like Firefox)
  • Powerful Quick Search
  • and more!

Is it hard to switch to Thunderbird?

No!  Simple and intuitive, yet fully featured, Thunderbird has all the functions you’re used to. Setup’s a Snap!  Thunderbird takes just a few minutes to download over a slow connection and seconds over a fast connection. The installer gets you set up quickly, and the new Easy Transition system imports all of your settings – e-mail account user names and passwords and sent/saved messages from Outlook/Outlook Express and other mail clients – so you can start e-mailing right away.
