Opera is a web browser and internet suite developed by the Opera Software company. The browser handles common Internet-related tasks such as displaying websites, sending and receiving e-mail messages, managing contacts, IRC online chatting, downloading files via BitTorrent, and reading web feeds.

Product Shot 2 Opera is offered free of charge for personal computers and mobile phones, but for other devices it must be paid for.

Features of Opera include tabbed browsing, page zooming, mouse gestures, and an integrated download manager. Its security features include built-in phishing and malware protection, strong encryption when browsing secure web sites, and the ability to easily delete private data such as HTTP cookies.

Opera runs on a variety of personal computer operating systems, including Microsoft Windows, Mac OS X, Linux, FreeBSD, and Solaris. Evaluations of Opera have been largely positive, and it has innovated or pioneered many key features of modern browsers. Despite these factors, Opera has captured only a small fraction of the worldwide personal computer browser market. It does, though, have a stronger market share on mobile devices such as mobile phones, smartphones, and personal digital assistants. Editions of Opera are available for devices using the Symbian and Windows Mobile operating systems, as well as Java ME-enabled devices. Approximately 40 million mobile phones have shipped with Opera pre-installed. Opera is the only commercial web browser available for the Nintendo DS and Wii gaming systems. Some television set-top boxes use Opera. Adobe Systems has licensed Opera technology for use in the Adobe Creative Suite.


Opera started out as a research project in Norway's largest telecom company, Telenor, in 1994, and branched out into an independent development company named Opera Software ASA in 1995. Opera Software develops the Opera Web browser, a high-quality, multi-platform product for a wide range of platforms, operating systems and embedded Internet products.


Opera's vision is to deliver the best Internet experience on any device. Opera's key business objective is to earn global leadership in the market for PC/desktops and embedded products. Opera's main business strategy is to provide a browser that operates across devices, platforms and operating systems, and can deliver a faster, more stable and flexible Internet experience than its competitors.

Fast Facts

Opera Software ASA is an industry leader in the development of Web browsers for the desktop, device and mobile markets. The Opera browser has received international recognition from end-users and the industry press for being faster, smaller and more standards-compliant than other browsers, and it has gathered a cult following on the net.

I started with IE and later FF, but then I found Opera. I have used Safari on mac and tried Chrome and Safari on Windows. I still them all for testing. But Opera just is the better tool. A swiss knife compared to a butterknive.
It contains everything I need and more, without the need for extra plug-ins.

The best things are it's speed and light weight.
I'm at the moment runnning Opera with 8 windows containing 203 tabs!!! and the email client. And it stays fast as ever!
 I use a window for the mail and links I open form there, one for studies, and separate windows for the projects I work on. I've first started working like this with a similar amount of tabs on my old Pentium 4 (2.8GHz 1GB): I was used to Firefox crashing or getting real slow after a few hours until I noticed the enormous amount of data I could have for reference without having to reopen everything every few minutes for bookmarks. 
When I'm not working on a project for some time I save the window. The only problem is restarting the browser, all these windows have to reload :P

Second best are the mouse gestures. I use the back and forward buttons on my mouse to switch between tabs and the gestures (that are faster) to do the navigating.

Opera Turbo, the compression system used on the mobile-phone version of Opera allows me to surf cheap on a payed per amount connection and fast on a mobile connections, without loosing the images (which you can also easily block).

I also like Opera-link, I can work on my phones, work-pc and portable with usb-version with all my links and notes and contacts.

And how about the most secure browser, for your safety and privacy. (BTW. Use a master-password, then it's about impossible to steal your passwords)

 Opera has its own rendering engine (presto) which is one of the best around. It has always been one of the best and most up-to-date engines around. This is a strong point, but also a weakness, not every website-builder knows Opera...
The only problems are in websites that are build by people that don't test there creations. Luckily more and more sites are build following to the w3c-standards.

Opera really is the best webtool I know.

theUg: #opera I use opera since late 2000 and version 5.12. It's more efficient than Firefox in memory usage (I have 43 tabs open right now and about 30-35 routinely - that would cripple my system if using Firefox). It's as fast and secure as Firefox or Safari. The main difference between FireFox and Opera is that latter is full fledged Internet suite which includes e-mail/RSS, and chat/IRC clients and many other functions while Firefox is strictly browser with virtually limitless expandability. The amount of default functions included in Opera could be too much for some and too little for others, but it works for me. Besides, if I have to install it on other machine, I'll have all the functionality right away (in a smaller download, I might add), plus instant synchronization using Opera Link (bookmarks, Express Panel, entered URI history, personal panel, notes etc.) instead of searching and downloading various add-ons and programs (like Thunderbird for e-mail).

keatsta: #opera I switched from Firefox when the 10.0 alpha first came out and I never looked back! Fast, reliable, light and with a wealth of features: Opera has everything I want in a browser. The support isn't quite as large as Firefox, but a creative user can replicate everything a rival browser has to offer with clever scripting. Nov 11, 09

dialupinternetuser: #opera I think that I would try out Opera if it wasn't for all of Firefox's amazing add-ons. And Firefox is prettier. The add-ons are the main reason however. I use Chatzilla daily and others make t browsing experience a lot nicer. May 20, 08

digitalscrap.net: #opera I remember when opera first came out. I supported it way back then, and am glad to see it still around. I never thought it would be a browser on my handheld video game system (nintendo ds) & its great. Opera browser was my savior when I only had dial up, I never forgot all the time it saved me!
