Opera is a web browser and Internet suite developed by Opera Software. The browser handles common Internet-related tasks such as displaying web sites, sending and receiving e-mail messages, managing contacts, chatting on IRC, downloading files via BitTorrent, and reading web feeds. Opera is offered free of charge for personal computers and mobile phones.
With the latest versions, there have been serious improvements to the support offered for modern web technologies such as CSS 3.0, XHTML, HTML5 and so much more. Opera has unfortunately lost a lot of their market-share to competition browsers like Mozilla Firefox and as Internet Explorer still remains king, IE9.
Features 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 websites, and the ability to easily delete private data such as HTTP cookies.
If you're having trouble with a lagging Firefox or IE9, give Opera a try. You might like it.
