Firefox add-on maps the sites you visit

Last May, I described the CallingID add-on for the Mozilla Firefox browser. It lets users see at a glance the address or location of the server hosting the site their visiting, and it even offers a color-coded security rating.

Unfortunately, the add-on doesn't work with Firefox 3, and the vendor's site doesn't offer any information on or help with this problem.

While looking for a solution to the CallingID glitch, I discovered Shazou, a Firefox add-on created by Chuck Durham at Seisan that goes one step further by showing the location of the site's server on … Read more

Google Chrome extensions: Not yet, but later

MOUNTAIN VIEW, Calif.--One of Firefox's initial claims to fame is the fact that the browser can be extended with a multitude of plug-ins, and even though Microsoft caught up with Internet Explorer, Firefox still has an extension edge over Google's new Chrome Web browser.

For now.

"We don't have that in the beta today, but we definitely plan an extension API," or application programming interface, Sundar Pichai, a Google vice president of product management, said at the Chrome launch event here Tuesday. "It is one of the things we will get to next.&… Read more

Featured Freeware: WebMynd

This Firefox extension takes a stab at solving a common Web problem: finding again that which you had found before. WebMynd adds two very useful functions to your browsing: site-by-site recording of where you've been, and integrating your history and Delicious bookmarks into specific Google searches. It's the Back button with brains.

The site-by-site recording creates a timeline view of your browsing and a photo browser-like display. Want the site you found Friday after lunch? Rewind using the Reel view. Looking for the site with the purple logo thing? The Grid view is good for your visual memory. … Read more

Apple extends MobileMe accounts--again

In an apparent attempt to make up for the problems that plagued MobileMe's launch in July, Apple has announced that it will extend user accounts another 60 days for free--that's on top of the 30-day free extension Apple gave users in July.

In an e-mail sent Monday to MobileMe subscribers announcing the extension, Apple acknowledged that the Web services suite needs more work:

We have already made many improvements to MobileMe, but we still have many more to make. To recognize our users' patience, we are giving every MobileMe subscriber as of today a free 60-day extension. This … Read more

Sifting open-source wheat from the chaff

BusinessWeek is asking an important question of open-source companies: despite the rapid growth of some open-source businesses (e.g., Red Hat, Novell Suse, Alfresco, SugarCRM, and others), it's still very much an open question as to whether open source can deliver outsized returns for investors.

"A pure service business is not particularly defensible," says [Red Hat CEO Jim] Whitehurst. "Some open-source companies have not truly figured that out." If the open-source movement, now in its second decade, is to realize its promise for vendors and investors, more of its purveyors will need to get the message soon.

Savio Rodrigues of IBM has been beating this drum for some time, suggesting that pure open-source business models have a built-in glass ceiling. While I think this is a bit overstated, I 100 percent concur that any business must figure out a "proprietary" differentiator that tells a customer, "This is why you buy from me rather than my competitor, and rather than taking it from me for free."

Support, as Jim Whitehurst suggests, is not a compelling enough argument for most would-be buyers.

This is why I've argued for a phased approach to open source. It's inefficient to try to "reap" every prospective customer in the early stages of a business: making the code open source lets a company sow a wide field of prospective buyers.

But it's also inefficient to rely on faith and goodwill to reap customers later in a company's growth and revenue trajectory. There must be a compelling reason to buy. This is where many in the open-source world lose their way. But what should that reason be? That is the nettlesome question.… Read more

Featured Freeware: PDF Download

The problem with opening PDF files in Firefox is that it tends to slow down your performance, especially if you open a number of them. This simple little extension gives you complete control over PDF files in a Toolbar button.

Rather than stick you all alone with a browser-jarring PDF file, the PDF Download extension provides you the option to: download the file locally, open it with Firefox using the PDF download options settings, view the PDF as an HTML file in the browser, bypass PDF Download, or cancel the link. The first two options are self-explanatory, while the "… Read more

Featured Freeware: PicLens

Cross-platform, cross-browser, and proud of it, browser plug-in PicLens is to Web surfing as an IMAX screen is to a 13-inch laptop monitor. In theory, it takes the images it finds on a Web site, expands them to super-extra-large size, and then lets you surf through them in a classy scaling interface that we think we last saw in Iron Man. Or maybe it was The Dark Knight.

Installing it places a button on the Toolbar. When you're on a PicLens-enabled Web site, click the PicLens button to activate the PicLens interface. Your screen will go black, and all … Read more

Digg launches Firefox toolbar with live notifications

Digg has just released a new extension for Firefox 3 that integrates whatever page you're on with the popular social news site. Included are handy things like a real-time pop-up window that notifies you when friends have dugg something, or when new stories hit the front pages of various sections. There's also a toolbar that can be toggled on the top of your browser which shows you if a page you're on has been submitted to Digg along with options to submit it yourself or read the user comments.

The extension only works in Firefox 3 but … Read more

An online video safari

Don't be deceived by this Firefox extension's unassuming user interface; it's a very capable video player.

NetVideoHunter operates via a tiny icon and counter that appear in your status bar. When you click on the icon, a window appears for viewing videos. We liked the step-by-step guide that walks you through the process--a definite plus for novice users. There is a link that's supposed to offer information on how to play FLV files, but clicking it didn't produce anything. On our first try, we visited the ever-popular YouTube. We clicked on a video and as … Read more

Power Downloader revitalizes old add-ons

Whenever Firefox gets a major update, Power Downloader gets asked the inevitable question: what do I do if my favorite extension hasn't been updated yet? This time, Power D was asked by Kitty Kilobyte's cousin's sister's best friend forever, Tessa Terabyte. In her office, Tessa said, she has to copy text from Web sites and paste them into e-mails, and she used the extension called AutoCopy to help her do that.

AutoCopy is a highly useful extension. By simply highlighting a string of text, it would copy to the clipboard, and open a small menu asking … Read more
