Opera features

Efficient surfing

Tabbed browsing

Surf the Web easier and faster by opening multiple Web pages within the same application window.

Integrated search

Search Google, eBay, Amazon and more with Opera's integrated search. You can also search directly in the address field using shortcuts (e.g. "g" for Google).

Pop-up blocking

Opera lets you control whether to block all pop-ups, or open only the ones that you have requested.

Fast Forward

Fast Forward will detect the most likely "next page" link and greatly simplify navigation in multi-page documents.

Password manager

Opera's password manager remembers your usernames and passwords so you will not have to.

Sessions

Save a collection of open pages as a session, for later retrieval, or start with the pages you had open when Opera was last closed.

Quick preferences

Pressing F12 displays Opera's 'Quick preferences' menu to easily switch settings such as browser authentication, pop-up and cookie preferences.

Notes

Notes can be kept in conjunction with a Web site you want to refer to later, to remind you of any particular information you may like to review again.

Voice

The voice feature allows you to control Opera's interface by talking and to have documents read aloud. Voice is currently offered in English and runs on Windows 2000 and XP.

Security and privacy

Security bar

Opera displays security information inside the address bar, located next to the padlock icon that indicates the level of security present on a site.

Cookie control

Opera gives you detailed control of what cookies to accept and reject, such as allowing for different set-ups for different servers.

Opera mail

Opera's built-in POP/IMAP E-mail client is a combined e-mail program, news reader, mailing list organizer and RSS/Atom newsfeed reader.

Communicate with people all over the world using Opera's IRC chat client. Chat privately or in rooms, or share files with your friends and family.

Customization

Drag and drop

Using the 'appearance' dialog you can make Opera look almost any way you want. Move buttons and search fields, add and remove toolbars, and so forth.
