Some of the default mouse gestures include:
Opera 5.10, released April 2001
Around April 2019, Opera removed this functionality in its desktop browsers and it's no longer supported on desktop. The fate of it on its mobile browsers is uncertain.
Opera's original privacy feature, Private Tabs, allowed users to open a private browsing session in a tab in the current window, instead of a separate window. It would not record browsing history, use the web cache, or stored passwords, and would forget any information accessed in the Tab when it is closed. This feature was replaced by Private Windows in Opera 15. Opera 10.50 (Tabs) / Opera 15 (Windows)
This tool is directly tied to NetCraft and Phishtank, thereby serving as a phishing filter as well as real-time fraud protection.
The user can select the desired search engine via a list or by using keywords in the address field. Example: Opera has a pre-set keyword for using the Google search engine: "g". Therefore, if a user types "g Wikipedia" directly into the address field, Opera performs a Google search for "Wikipedia". Other keywords are included, including "b" for Bing, "y" for Yahoo! Search, and "w" for Wikipedia. Users can also customize their own keywords. Opera 4, released 28 June 2000
Opera 49
Users are able to save all the tabs in a window as a Speed Dial group, manage the saved links, and open them all later if wished. Opera 9.2, released 11 April 2007[11]
Furthermore, other browsers including, but not limited to; Google Chrome, Safari, and Internet Explorer have or previously had a near identical feature. Although not necessarily branded as Speed Dial, it may be informally referred to as Speed Dial in non-Opera browsers or with 3rd party browser extensions that add the feature, considering that the feature first debuted in Opera browsers.[12]
Opera 11, released 16 December 2010
Opera 4, released 28 June 2000
Many notable features, there were available in older versions of the Opera web browser, were removed when Opera switched from its legacy layout engine, Presto, to the Chromium-based Blink engine. Presto was introduced in 2003 (Opera 7) and was used until Opera 12.18, in 2016.[14][15][16][17]
g , yt and w prior to the search string launches a search using Google, YouTube and Wikipedia respectively.Opera 9, released 20 June 2006
Opera stores its content-blocking URL list in a file called urlfilter.ini. Several internet sites provide a regularly updated urlfilter.ini already loaded with the web's most common advertisements so users can block ads using the built-in feature. The users are able to sync the content blocker list using Opera Link.
Skins: Opera supports customized user-interface skins, allowing users to change the style and size of toolbars, buttons and menus. A drag and drop functionality allows the user to easily place links and buttons on toolbars. The user is able to install custom skins, ranging from color changes to OS mimics to animated GIF images.[19]
Toolbars: Opera provides toolbars that display different menus and buttons. For example, the "start" toolbar is a drop-down toolbar which can be enabled to provide access to history and bookmarks when the user focuses the address field. Additionally a "view" toolbar includes multiple shortcuts to control the page exhibition and a find in page tool, a "navigation" toolbar can show commands to navigate through webpages, etc.
Dragonfly is written using standard web technology and the Scope protocol, and source is available under the Apache License 2.0. Opera Dragonfly is compatible with Opera products using Presto 2.1 and later. The first stable version of Opera Dragonfly was released on 5 May 2011. Opera 9.5, released 2008
Opera 9.5, released 12 June 2008
Opera 6, released 18 December 2001
It is possible to control all main functions of the browser using only the keyboard, and the default keyboard shortcuts can be modified. Opera also supports the use of access keys to allow a computer user to immediately jump to a specific part of a web page via the keyboard.
Opera Link servers left users with only a month to backup their bookmarks one by one, before the feature was discontinued in 2015.[24] User data synchronization support was set to return in a later release, though users on Symbian, J2ME and BlackBerry would not have access to it. Opera 9.50, released 12 June 2008. 14 December 2015
This feature was replaced by Private Windows in Opera 15. Opera 10.50 Opera 15
Since version 32 this feature can only be achieved with a combination of Speed Dial and Bookmarks, or more elegantly by installing a session-manager extension.[25][26] Opera 4, released 28 June 2000 Opera 32, released September 2015
Not loading of tabs until they're selected after a session restore (lazy loading) - introduced in version 21 (along with delayed loading),[27][28] removed in version 46.[29][30]
Opera 8, released 19 April 2005
Common compatibility problems are caused by websites not following standards or using methods for detecting the browser being used. To cope with outdated detection methods or poorly built websites, Opera enables users to change the information that is sent to websites to identify what kind of browser is being used—known as the user-agent. In previous years, Opera came preconfigured to partially "cloak" itself as Internet Explorer, but still included the word "Opera" in the user-agent information allowing the browser to be counted in web browser statistics. As websites modernized themselves and Opera 9 became more compatible with IE code, Opera began to use its own identification by default.
Later versions of Opera offered a limited method of cloaking allowing selection from a pre-defined range of options including Mozilla and Internet Explorer. If needed, Opera can mask completely as Internet Explorer or Mozilla, leaving out the reference to Opera in the UA string and JavaScript objects. Some sites test only for objects that are not present in Opera.
The version 8 of Opera introduced a further provision for dealing with faulty coding, by providing a set of scripts in BrowserJS that rewrites known broken pages as they are being opened. The closely related UserJS (similar to Mozilla's Greasemonkey), allows users to run their own code at various times in the processing of a page. These techniques have allowed many popular but incompatible sites to be used fully with Opera.[34]
Opera periodically updates itself with the latest version of BrowserJS and override_downloaded.ini files to keep more sites working correctly in the browser, respectively, they serve to patch websites which would otherwise have issues to run on Opera and to cloak the UA string by default for some website domains.
