Opera Web Browser


Internet Explorer is the most popular Internet browser in the world. Yet, it is laden with security flaws and is the target of all sorts of evildoers. Internet Explorer comes pre-installed on Windows computers, but you don't have to stick with it. It's easy to download and use another Web browser. In fact, while Microsoft is busy trying to solve their Internet Explorer security problems, several other Web browsers have surpassed Internet Explorer in their sleekness, speed, and features. Opera is one such browser.
Opera can be downloaded at the Opera Software Web site. It installs quickly and easily. During the installation you are prompted to let Opera copy your Favorites from your current Web browser making the transition effortless. While Opera has an e-mail client, you don't have to use it. You can simply download Opera and use it as your browser.
Opera is less than half the size of Internet Explorer, yet it has several features that leave Internet Explorer in the dust. The first is called "tabbed browsing". When you open an Internet page in Opera, it will have a tab at the top of the page. Then when you open another page and it will also have a tab. This makes it simple to switch between Web pages; just click on the tab of the Window you want to view. It is also easy to see all the different pages you have open at any given time. It is perfect when you are researching any subject and is useful even for everyday Web surfing.
Another great feature of Opera is the ability to save the session you are working on. For instance, if you are researching a health issue and have five pages open, you simply click on Tools, then Preferences. Choose "Continue from last time" and close Opera. Next time you open Opera, you will be right where you left off. I keep this as my default setting so I don't even have to click on Tools or Preferences. Opera knows that I want to start each session showing all the Web pages that I was using in my last session.
My favorite Opera feature is called Mouse Gestures. Once this feature is turned on you can simply move your mouse to perform tasks that would otherwise require placing your mouse on a specific icon or menu choice. It works like this. Hold down the right mouse button and move the mouse to the left to go to a previous page. Hold the right mouse button and move the mouse to the right to go to the next page. There are mouse gestures for many frequently performed operations, and once you learn just a few them you can dramatically speed up your Web browsing.
The Opera Web browser is extremely customizable. You can use pre-formatted "skins" to change the look of the browser. Not only is this fun, but also, if you have any visual difficulties, you can choose a look that is easier on your eyes. In fact, you can even design your own buttons and choose your own colors if you don't find any pre-designed skins that you like. You can also customize the panels that appear on the left side of the Opera window to provide one-touch access to various functions. Opera even lets you create a Personal Toolbar where you can have direct access to your most visited Web sites.
That's not all. Opera has a pop-up blocker, a password manager and a download manager. You can zoom in and out to make the text larger by pressing the + and - keys. You can easily set the text size to whatever is best for your eyes. The printing functions are also better than those in Internet Explorer.
The best part is that all these great features don't cost anything. The free version of Opera has some ads at the top of the screen, but I find them unobjectionable and barely noticeable. If you don't like the ads, you can purchase a paid version without ads for $39. The paid version, also gives you better access to tech support. If you try the free version of Opera and like it, you may want to buy the paid version just to support a great company that is giving Microsoft a run for its money.
Whether you are trying to escape the insecurities of Internet Explorer or looking for a better Web browser, give Opera a try. There's a lot to like here.

Firefox Add-ons Enhance Web Browsing


Firefox is an increasingly popular and powerful Web browsing alternative. But installation is only the beginning of the fun. Hundreds of small software add-ons can teach Firefox exciting new tricks and tailor it to your individual needs and preferences in ways that other browsers can't match.
After installing Firefox, click Tools and then Extensions. For now, ignore the three grayed-out buttons and click Get More Extensions. This displays the main Firefox add-ons Web page that offers four kinds of add-ons: extensions, plugins, search engines, and themes.
Extensions are small programs that add new features to Firegox such as toolbar buttons, improved privacy and security, and easier operation. Almost two dozen extension categories are listed, with recently updated and most popular extensions highlighted separately. Clicking an extension's name shows you its information page that includes a description and version identification, the number of times it's been downloaded, browser versions supported, occasional user reviews, and a prominent Install Now button indicating the download's size.
Installation simply involves clicking the button, following instructions, perhaps setting options, and restarting Firefox. Extensions make me even more enthusiastic about Firefox. I'd hate to lose AdBlock (blocks annoying Web ads), Print Preview (adds toolbar button to show how Web page will print), Session Saver (remembers Web pages open when Firefox is closed), and Hyperwords (makes every Web page word a link for searching, e-mailing, and more). While extensions are quite safe and easily removed, for caution I suggest avoiding the newest of them with low version numbers and only a few downloads shown.
After you install extensions, the Uninstall, Options, and Find Updates buttons in the Tools/Extensions dialogue box will be enabled. Remove extensions by selecting them, clicking Uninstall, and restarting Firefox. Click the Options button to explore and customize a selected extension's capabilities and settings. Click on Find Updates occasionally to ensure that you're running current extension versions, especially after installing new Firefox versions since they may require updated extensions.
Plugins are programs that allow Web site content to appear in your browser instead of in separate applications. They are available for Acrobat Reader, Flash Player, Java, Quicktime, Realplayer, Shockwave, and Windows Media Player. You can install plugins you know you'll need or wait to be prompted when you attempt to display content that needs one.
One of Firefox's friendliest features, the Google search, isn't widely used. It's text entry area is located to the right of the display window for Web page URLs, near the upper right corner. It initially shows the Google "G" logo, indicating that it's ready to search Google. Enter a search term, press Enter, and you'll see Google's results. Firefox is also configured with a few other search engines. Click the G-logo for a drop-down menu of other sites which can be searched the same way, and several dozen other search engines can be installed from the add-ons page.
Finally, the add-ons page offers different browser skins or themes that allow you to personalize the browser's look and feel. A theme can simply change colors, or it can tweak every aspect the browser's appearance.
Firefox is one of the Mozilla Foundation's two main applications. Thunderbird, an e-mail client, is the second and has similar add-ins available Let's be grateful for such useful software, written by volunteers, available free of charge.

Identity Theft Tips


Identity theft is a serious concern in today's high-paced technical world. There are many Internet users worried about phishing schemes, bogus Web sites, and online credit card theft. Yet, a recent survey reports that identity theft is more often initiated from paper sources rather than the Internet. The 2005 Identity Fraud Survey sponsored by the Better Business Bureau, VISA, Wells Fargo and CheckFree Corporation, contradicts the common belief that most identity theft is performed online.
Ken Hunter, CEO of the Council of Better Business Bureaus, reiterates the essence of the report. "Most instances of identity fraud occur through traditional channels and are paper-based, such as a lost or stolen wallet, a checkbook, credit card, a piece of mail. By making a few, simple changes, consumers can improve their identity safety and help protect themselves against this type of fraud." Hunter said that Internet users who watch their financial accounts online are often able to detect fraud earlier than those who rely the usual mailed monthly paper statements.
The report also sites that these crimes are more likely to be committed by someone you know rather than a stranger. So while you keep alert to online schemes, don't get complacent about your everyday financial paper trail. Experts advise that you don't carry your social security card or number in your wallet, that you shred any financial documents before trashing them, and that you carefully monitor incoming and outgoing paper mail.
Be careful out there!

Ultra-Mobile PC


Are you ready for yet another cryptic abbreviation to add to your high-tech acronym repertoire? You should be, because the device being called the UMPC (Ultra-Mobile PC) may be just useful enough to really catch on.
The UMPC began as Project Origami, a joint development exercise between Microsoft, Intel, and Samsung, and is a small lightweight computer (approximately two pounds) that uses the Windows XP Tablet PC operating system. Its seven-inch or smaller diagonal display is equipped with an integrated touch screen. They connect to the Internet through a wireless WiFi connection in your home or via a hotspot, or with a Bluethooth-enabeled wireless phone. These fully-functional PCs will allow you to check news and weather, send and receive email, work in Office and other software programs, and play music and games.
Microsoft has already announced UMPC models by Samsung, Asus, and Founder. Founder is currently shipping their UMPC device in China. Samsung will soon debut their unit in Korea. No formal launch date for the U.S. has been set by any of these companies.
Although many different manufacturers currently produce tablet PCs, they are larger and more cumbersome. The UMPC may be just small and connected enough to create a niche for itself.

Vulnerability Found in Some Symantec Products


We often hear about vulnerabilities in Microsoft products that allow viruses to enter computers. Today, however, the news is about a virus attacking through a weakness in software that is supposed to protect you from such attacks.
eEye Digital Security, a noted security vendor, recently provided an alert regarding a susceptibility in Symantec Antivirus that allows a hacker to infiltrate and take control of a computer system that is running certain Symantec software. Shortly after the eEye's alert, Symantec confirmed the veracity of the story. The finding of this security flaw is of special importance since Symantec is one of the world's leading makers of antivirus software.
Fortunately for home users, the flaw is found only in Symantec Antivirus Corporate Edition and Symantec Client Security 3.x. Home users of Norton Antivirus and Norton Internet Security products are not at risk. Symantec is working on a patch to eliminate the problem and will download the fix to corporate users as soon as it is available.

Sony Handycam DCR-VX1000


Thank Sony for introducing digital video editing to the desktop. Before it released the Handycam DCR-VX1000, if you wanted to edit video on a PC you had to invest thousands of dollars in an expansion card to digitize analog footage. The DCR-VX1000 was the first camcorder to capture in the mini-DV format, and the first with a FireWire port for transferring digital video to a PC. The DCR-VX1000 cost nearly $4000, but it offered dramatically better video quality, and less-expensive models soon followed. For more, see Sony's

BlackBerry 850 Wireless Handheld (1998)


Canadian firm Research in Motion didn't invent e-mail, wireless data networks, the handheld, or the QWERTY keyboard. But with the little BlackBerry, along with server software that made e-mail appear on it without any effort from the recipient, RIM put it all together in a way that even nontechie executives could appreciate--and thereby opened the eyes of corporate America to the potential of wireless communications. So addictive that some call them CrackBerries, RIM's ubiquitous e-mail communicators--especially their high-res displays and small yet serviceable thumb keyboards--have forever changed the design aesthetic for personal digital assistants, while their approach to e-mail has become the standard by which all connected handhelds are measured.
