Features[edit]Opera includes built- in tabbed browsing, a bookmarks bar, add- ons, and a download manager. Opera has "Speed Dial", which allows the user to add an unlimited number of pages shown in thumbnail form in a page displayed when a new tab is opened. Speed Dial allows the user to more easily navigate to the selected web pages. Usability and accessibility[edit]It is possible to control some aspects of the browser using the keyboard shortcuts.[3. Page zooming allows text, images and other content such as Adobe Flash Player, Java platform and Scalable Vector Graphics to be increased or decreased in size to help those with impaired vision.[3. When the Opera Turbo mode is enabled, Opera compresses requested web pages (but not HTTPS secure pages) by up to 8. This process reduces the total amount of data sent and is particularly useful with slower Internet connections, making pages load faster, or when there are restrictions or costs dependent upon the amount of data transferred.[3.
This technique is also used in Opera Mini for mobile phones[3. Privacy and security[edit]One security feature is the option to delete private data, such as HTTP cookies, browsing history, items in cache and passwords with the click of a button.[4. This lets users erase personal data after browsing from a shared computer.
When visiting a site, Opera displays a security badge in the address bar which shows details about the website, including security certificates.[4. The browser checks the website that is being visited against blacklists for phishing and malware, and displays a warning page if it matches any of these lists.[4. In January 2. 00. Asa Dotzler of the competing Mozilla Corporation accused Opera Software of downplaying information about security vulnerabilities in Opera that were fixed in December 2. Dotzler claimed that users were not clearly informed of security vulnerabilities present in the previous version of Opera, and thus they would not realize that they needed to upgrade to the latest version or risk being exploited.[4. Opera responded to these accusations the next day.[4. Standards support[edit]Opera was one of the first browsers to support Cascading Style Sheets (CSS).[4.
With the adoption of the Blink layout engine, web standards support of Opera should be similar to Google Chrome. Development stages[edit]Opera Software uses a release cycle consisting of three "streams" (which correspond to phases of development) that can be downloaded and installed independently of each other: "Developer", "beta" and the unnamed final release.
New features are first introduced in the developer build, then, depending on user feedback, progress to the beta version and eventually released.[4. The developer stream allows early testing of new features, mainly targeting developers, extension creators, and early adopters. Opera developer is not intended for everyday browsing as it is unstable and is prone to failure or crashing, but enables advanced users to try out new features still under development, without affecting their normal installation of the browser. New versions are released frequently, generally a few times a week.[4.
The beta stream, formerly known as "Opera Next", is a feature complete package, allowing stability and quality to mature before the final release. A new version is released every couple of weeks.[4. Both streams can be installed alongside the official release without interference.
Each has a different icon to help the user distinguish between the variants. Devices[edit]. When a user browses the web using Opera Mini, the request is sent via the General Packet Radio Service (GPRS) to one of the Opera Software company's servers, which retrieves the web page, processes it, compresses it, and sends it back to the user's mobile phone. In addition to the edition of Opera for personal computers, there are versions for a variety of devices. Opera Mini is a microbrowser designed primarily for mobile phones, but also for smartphones and personal digital assistants. Versions up to 4 used the Java ME platform, requiring the mobile device to be capable of running Java ME applications.
The microbrowser began as a pilot project in 2. After limited releases in Europe,[4. January 2. 00. 6.[5.
