add-ons

Dr. Web helps you minimize contact with unsanitary files before you download them, by scanning them in advance and letting you know before it lands on your desktop if the file has a clean bill of health or if you should put on your biohazard suit before handling the innocuous-looking critter.

This is not new, but I just saw it the other day, installed it, and liked it: Tab Effect. It's a plug-in for Firefox that adds a rotating cube effect to your screen when you change from one tab to the other. So, from a distance, people looking over your shoulder might think you're user switching on a Mac or using a much geekier Linux-based OS. And actually, I find Tab Effects adds a bit of situational awareness to my tabbed browsing experience, since the rotation of the cube matches the direction the new tab is from the … Read more

I'm used to visiting the official Mozilla add-ons site to grab my Firefox extensions, but there's a new option in town for Facebook app-aholics. It's called Rock Your Firefox, and it accomplishes nearly the same thing as does the Mozilla add-ons site, but in a simple Facebook application. Its "killer app" is that it keeps track of what themes and extensions your friends have downloaded and recommend--a process that usually requires nosing around their browsers.

Each add-on has its own landing page, along with a list of people who recommend the application. You can sort … Read more

Surfing the Web doesn't have to be a solitary experience, at least according to Me.dium, a browser add-on that uses real-time data to share information with your friends and the Me.dium community. Today, Me.dium added support for Internet Explorer 7, opening up the "social surfing" experience to a huge new audience.

In essence, Me.dium lets you share as much of your browsing information as you like with either a select set of friends, Me.dium users who are visiting a specific Web page, or the Me.dium community at large. The extension presents itself in a browser sidebar and displays your Me.dium universe, or "your online world." The map is based on your current Web location, your friends' current browsing spots, and your recent Web activity.… Read more

In the spirit of my recently sworn allegiance to the powerhouse add-on Tab Mix Plus as the "best Firefox extension ever," I've created a resource guide for all of the features and options available in the Firefox add-on.

In a nutshell, Tab Mix Plus lets you customize nearly every detail of the appearance and behavior of your tabs without having to get into any of the about:config settings in Mozilla Firefox.

One important note: my Tab Mix Plus guide is based on the default Firefox theme. If you use a different theme, some of the Tab Mix Plus options may be affected. Also, this guide was written using Tab Mix Plus 0.3.6, which is important to note because the add-on does update semi-frequently.… Read more

Nearly every time I meet with a representative from one of the Web browsers, the questions of "Which browser do you use?" and "Why?" inevitably come up. The answer to the first is still Mozilla Firefox, like most people I know. The short answer to the second is "extensions," which is an easier way of saying "more functionality and personal customization."

The follow-up question is invariably, "What's your favorite extension?" and that's much harder, because it's not any one particular extension that makes Firefox great--it's the … Read more

Mozilla enjoys a large development community to build add-ons for its Firefox browser. Now it seems all that development might not be a good thing. A security researcher in Indiana has found that the process used to update some of these add-ons automatically appears to be flawed, allowing criminal hackers to intercept the browser's call to the developer to see if there's a new version available. Worse, the most vulnerable add-ons aren't from vendors you've never heard of; they include brand-name sites like Google, Yahoo, Facebook, and LinkedIn.

Extensions for Firefox contain hard-coded Internet addresses for … Read more

Mozilla Firefox gets a lot of praise for the countless third-party extensions that add features like FTP, download management, and tab customization to the open-source browser. The most popular browser on the market, Internet Explorer, also has its fair share of add-ons, but nowhere near the number or quality of its competitor.

One new download for Internet Explorer, however, adds a number of valuable features that are only replicated in numerous different Firefox extensions. Among its many enhancements, IE7Pro adds tab management, ad blocking, Flash blocking, crash recovery, and the ability to re-open closed tabs to the Microsoft browser. Even cooler, it allows user-based scripts much like Greasemonkey for Firefox. Again, the scripts aren't nearly as impressive as Greasemonkey, but the idea is a good one.

Digg launched an API recently, a way for developers to write new ways to submit stories to Digg and to extract data from the service. One intriguing new app that uses the API is the Smart Digg Button for Firefox. There have been toolbar icons that make it easier to Digg stories before, but what this add-on does is a little different. It tells you, in the lower-right corner of your browser, how many Diggs the page you're visiting already has. If you click on the notification, you can add your own Digg, too.

It's a cool idea … Read more
