Open It

Open IT Online allows you to open your documents and images online without the need of any software to be installed.

Open IT Online is easy to setup and allows to choose, among different online services, which one you want to use for each type of file supported.

Every time you will get the "Open with..." dialog within Firefox (i.e., after a click on a link to a document/spreadsheet/presentation), you will see the size of the file you are going to open and you will have the possibility to choose which online service to use.

Fast Dial

Fast access to your favorite sites through thumbnails, like Opera Speed Dial.

I really like this one, it's fast and easy and completely customizable to the sites I visit the most.

After you install you simply hit the command, "t" shortcut (for mac). and when you open a new tab, all of your sites you loaded into Fast Dial come up in nice neat little boxes.

Video Download helper

The easy way to download Web videos from hundreds of YouTube-like sites. This works also for audio and picture galleries.

You Tube is great but there are some video clips that I want to add to my personal collection. Video Download Helper makes it really easy.

You pick the site, press play on the the video, go up and click on the Video Download Helper icon that rest in the top of the broswer bar.

Glubble

Glubble Family Edition is a free parental control suite for Firefox. I just installed this for my kids who are getting old enough to surf the net by themselves.

They start on a homepage with pre arranged sites that they can visit, and then you have the option to add other sites to the "Family Glubble".

The best idea here is that if one of your kids tries to access a site that is not approved, a pop up window comes up, and before they can view the site they have to email you and gain access.

This comes in handy with a 7 year old that knows how to spell!

I'm a big fan of Fire Fox, I've been using it since version 1. They are on the cutting edge of what a web browser can do. They had multiple tabs, and folders in your bookmark bar way before any else.

And they are aggressive about improving their product. Just check out some of the add- ons you can download and install to customize your web experience.

One of my recent add-ons is PicLens

PicLens

Full-Screen, 3D -- PicLens transforms your browser into a visually stunning experience for enjoying online photos and videos.

This is a great add on for designers who are constantly using google image search or flickr looking for inspiration. PicLens also supports YouTube, so think floating video wall!
