Opera 9.50 Build 9807 Beta

Opera started out as a research project in Norway's largest telecom company, Telenor, in 1994, and branched out into an independent development company named Opera Software ASA in 1995. Opera Software develops the Opera Web browser, a high-quality, multi-platform product for a wide range of platforms, operating systems and embedded Internet products.

Opera is known as the fastest and smallest full-featured browser, a first choice for people using older PCs and Windows 95 and a brilliant alternative to the default IE from Microsoft. Opera, first of all, is client World Wide Web, that is the program for extraction of the information from WWW as the documents created with help HyperText Markup Language (language of a marking of hypertext HTML).

The world's fastest...now even faster. Even though it's hard to imagine, we made Opera faster.
Following the release of Opera 9 last year, we re-wrote Opera's rendering engine for the coming Opera 9.5 release. As a result, Opera 9.5 contains more than a year's worth of speed, standards and performance improvements. Some enhancements include:

Some enhancements include:

Faster and less-memory intensive ECMAscript engine
A greatly improved layout algorithm
The font-rendering speed is improved significantly, along with the tiling of bitmaps
More responsive user interface

Internal benchmarks show up to 50 percent increase in speed compared to the previous core version in Opera 8. But, performance is more than just showing Web pages faster. Performance is about making your browsing experience more enjoyable and productive. In the past, we introduced much-loved and powerful features like Tabbed browsing, Mouse gestures, Fast Forward and Rewind, Speed Dial all designed to make you get more out of your time browsing the web. With Kestrel we add another powerful feature to this family:

Changes in Opera 9.50 Build 9807 Beta:
This build demonstrates the plugin work that has been done recently. Most of this work is not visible and is only testable through regression testing: compare with an older build and see if something broke. A lot of this work is cross-platform, so we would appreciate feedback on plugins on all platforms. Note, however, that a lot of the bugs around plugin detection are still unresolved, so this work is only testable on the plugins that you can actually see.

Known issues

"Save to download folder" is broken
Format selector when saving pages is broken.
Inline find stops working after entering one letter (using Ctrl/Cmd+F still works as expected).

Changelog

Fixed text selection when selecting from bottom left to top right
Crashing plugins should no longer crash Opera on Mac and Windows. Please test.
Fixed crash when opening certain files (especially PDF files)
Fixed crash when changing interface language
Some changes have been made to the tab mode "Activate first tab opened from current tab" (whose name might change in the future): If you open several tabs in the background from one page, Opera will remember that they are related and will switch focus between them when you close one of them. In the previous weekly you had to close the parent tab before this occured.
Windows: Tray icon is now gone if you don't have mail enabled
