Thanks to its extensibility, Firefox quickly became the favorite browser for most power users. But while extensions are a great way to make Firefox more functional, Mozilla's designers are also currently thinking about a complete redesign of the way the browser looks and feels, in order to keep up with changing usage patterns.

We’ve put together a list of 30+ must-have Firefox 3 extensions that we know you’ll enjoy, whether you’ve upgraded to Firefox 3 and are looking for something new to add to your browser, or have yet to make the upgrade and are looking for a reason.

One of the reasons behind Firefox's popularity is the availability of a vast library of extensions. Users use them to modify the browser to their liking and make their browsing experience easier and more pleasant. The problem is, unbeknown to them, these extensions are exposing them to risk.

Now, a lot of people publish lists of 'best' extensions. It's quick and easy to make these lists. One difference between my list and some of those "99 Must Have, Best Firefox Extensions!" is that is the real list of the extensions that I use every day. These don't just sound good, they work well.

Firefox is a very useful and feature-rich browser, we all know that. But aside from being a robust Web browser, Firefox is appealing to more sophisticated users because of the support that it gets from third-party application developers.

I want to take a detailed look at turbo-charging the Firefox browser with an elite selection of Google utilities. Firefox has its critics and its failings, but it has now been downloaded in excess of 400 million times: and as they say “what flies eat, they can’t all be wrong!” Firefox is pretty good out of the box, but everyone knows that the functionality of Firefox is extended massively by the simple addition of extensions, security issues nothwithstanding.

One of the major reasons Firefox is approaching 400 million downloads is because of how customizable the browser is thanks to extensions. In a way Firefox extensions are bittersweet, because they can provide some unique and useful features, but at the same time they can cause some unwanted problems.

Installing these Firefox extensions, like installing any other Firefox extension, is just a matter of clicking the shiny green Install Now button from the extensions' homepages. You'll find both the extensions enabled after a browser restart to complete the installation.

Konqueror as a web browser still unfortunately lags quite a way behind Firefox in terms of compatibility. For that reason, many KDE users stick with Firefox, despite the poorer integration between the desktop environment and the browser. I have just come across a theme for Firefox 3.0 designed to make Firefox fit in better on a KDE 4.0 desktop
