Opera – один из самых быстрых и гибких в настройке браузеров. Используя скины, пользовательские панели и другие средства настройки интерфейса, его внешний вид можно изменять до неузнаваемости. Программа позволяет "на лету" отключать и включать графику, а также может похвастаться фирменной технологией масштабирования веб-страниц, благодаря которой пользователи браузера практически никогда не видят горизонтальной прокрутки.

What's New in This Release:

Address field

An improved address field makes it easier to stay safe on the Web, and it now hides the complexity of long web addresses. It also provides more security information to help you stay safe when browsing; just click the badge for the website to see security information about the site you are visiting.
All webpages get a badge to the left of the address field. The badge replaces protocols like HTTP, HTTPS, and opera:, which are shown only when focusing on the address field.
Clicking the badge provides a easy overview of the potentially more complex security state of the current web page.
Parameters at the end of web addresses are visually hidden until the address field is focused. You can disable this with opera:config#UserPrefs|HideURLParameter if you still want to see the whole address all the time.
There is now a badge indicating that you are browsing with Opera Turbo on. Clicking this badge gives information about estimated data savings for the Opera Turbo session.

Auto-update

An improvement to auto-update now makes sure you have the latest extensions and Opera Unite applications.

Extensions

Opera extensions offer a way for you to easily add new functionality to your Opera browsing experience. Developers can easily create extensions using open standards (HTML5, CSS, javascript) and supported APIs. Opera extensions will be based on the W3C Widget specifications and this is being considered for an Open Standard effort.
Extensions will now run on secure sites (HTTPS) by default, and we have added a privacy setting where you can allow/disallow extensions to run on secure connections or in privacy mode (disabled by default).
Extensions now have a preferences page. Both the options page and privacy settings can be accessed from the extensions manager.

Some changes to requirements that will affect currently available extensions include:
Extensions must include an access request for the pages you want to access with the background process. You can do this by adding <access origin="http://example.com"> to the config.xml
Extensions must include an index.html file in the package, or include a <content src="someStartFile.html"/> in the config.xml.
Extensions must use broadcastMessage() properly:
broadcastMessage() only takes one argument: a string or an object literal.
So, use either broadcastMessage("hi"), or broadcastMessage({'say': 'hi' }

Mail panel

The Opera Mail panel has been improved with the following changes.
Decide which sections to show, and in what order.
Create folders to organize your mailing list and newsfeeds.
Filters are now called labels. Existing labels, custom labels and saved searches (as labels) are now located together under the Labels header in the Mail panel. The old filters, labels, and saved searches are now merged into the new, more powerful labels
In each category, (Attachments, Labels, Feeds, etc.) select which individual items to show and which items to hide.
Feeds can now be displayed in the panel without the need to enable a mail account.
The Mail panel automatically appears whenever you switch to a mail tab, and automatically returns to the previous state of the panels when moving back to a non-mail tab.
POP accounts now have Inbox and Sent views for themselves.
Multiple scrollbars are now changed to one global scrollbar for the mail panel. The scrollbar keeps section headers on top, which allows you to quickly scroll back up to them.
All mail search fields are now consolidated into one. This enables you to search wherever you want, with the help of a new toolbar that appears when searching.
You can save a search as a rule that will automatically label all the matching messages.

Plug-in loading

You can now set plug-ins to load only when you click on them, to significantly speed up browsing.
