Opera 10 alpha shows off new Presto rendering engine
By Tim Conneally | Published December 4, 2008, 4:40 PM
The Opera team has unveiled an alpha version of its Opera 10 browser, intended to show off the speed and feature support of the new Presto 2.2 rendering engine.
The first public preview of Opera 10 is available for download now, and a first look chiefly shows off the rendering speed of Presto 2.2 on resource-intensive sites. The browser quickly passes the Acid 3 Test, a feat that Opera first accomplished just this year. In BetaNews tests this afternoon, neither Firefox 3 nor Google's Chrome browser could pass.
Also key to this release are the additional Web standards Presto now supports. These include Web Fonts, the CSS 3 module for using custom fonts on a Web page that may not be available on a visitor's computer. Support for Alpha transparency and "color: transparent" settings has also been added.
For users, this early build of Opera 10 has added inline spell checking in certain fields, such as Facebook wall comments, and an auto-update function that keeps the browser build current when opted on.
Opera Mail, meanwhile, now supports either full HTML formatting or plaintext in e-mails, and the Dragonfly debugging tool has been improved to allow DOM editing and HTTP header inspection.


I'm glad Opera continues. It's a fantastic browser. For me, FF is my default browser, but Opera is always open and gets used about 50% of the time. Been the case since it first came out years ago. I find each have their very strong pros and cons I wouldn't want to do without.

|Opera _ one of the nicest to use and safest browsers (re secunia no known exploits are left unpatched).
Opera alpha 10 is an alpha and not a final release - so expect problems and have some fun testing.
I love to tweak and add items, buttons, content menu extras, and tinker to no end with this browser. It is a customization dream come true.
Safe, fast and reliable.
The apparent lack of the adblock can be replaced by the urlfilter.ini or the content blocking by either default lists or "on the fly".
No Scripts is possible in Opera with custom site configurations to allow content for desired sites and block the other sites globally. Ditto for accepting the cookies. It is all there, but in a different approach - it is already built in the browser ready to be used.
Been playing with custom adblocking.css and .js and find out that these are very good to block bad or unwanted content.
Nothing like these really should be limited to some third party extentions/addons that are needed for other browsers if the browser comes with these features.
Oldsod.

|Until I can install Adblock+/NoScript/Snaplinks and Firebug into Opera, it just doesnt get installed

|I gotta say I'm pretty happy these days that Opera doesnt have any extensions...

|Opera well not a bad browser still suffers from 1990s cookie handling, failure to load pages here and there completely or gets stuck thinking about what to do then freezes.
I keep Opera around for something to play with but serious work requires a browser that consistently works. Opera just does not do that for me. YMMV
Score: 0
|I wonder what 2000s cookie handling means... For me, this version is competely stable.
"but serious work requires a browser that consistently works"
LOL, if Opera not consistent (being an all-in browser), what is?
Score: 0
|I do not see any great increase in speed at all and if there is any, the human eye cannot see it :) .. I dislike the way Opera does things, but all in all, not a bad browser, just not for me.

|though my default browser on XP is opera 9.62 stable ..i find Opera 10 is not good for my PC ..it disables my mail client when i tried to downdgrade ! bt it's not actual opera 10, it's actually a preview of new presto engine 2.2 ..when keep ur fingers crossed !
Score: 0
|That's your fault... First, it installs next to 9.62 by default, not overrides it. Second, it has been said, it works with an other e-mail storage format which is not backward compatible with the old one. It's an alpha, read first, install second...
Score: 0
|It is not much faster than other browsers, the cookie systems is still the same and I detest the way Opera handles cookies.
It is not a bad browser, it just don't offer anything to make me change from FF2. the speed difference is not enough to make me lose my add ons and extensions I have with FF2.

|Fast is a bit depend your PC system.
With Core 2 Duo render faster But not too much. About %5 faster.

|That's a good news. :)
But hey, where's the comparison with IE and Safari?
Score: 0
|It crashed when I tried to make use of Wand, it froze when I attempted to view My Yahoo Mail account. It's certainly not faster than Firefox, and not as fast as Chrome. It's an Alpha so will not be posting comments like Opera is wonderful just yet, if ever. The days of these minority browsers are long gone, Firefox will be the next to sink into the sunset, and all that will remain will be IE.8 and Chrome, and that's all we need anyway.

|"not faster than Firefox"...that's funny - not even close. I will agree it's pretty unstable (alpha).
Score: 0
|I totally agree that both Opera and Firefox aren"t sustainable as currently configured. They both lack the financial support necessory to play with the big guys. Unless they can find a sugardaddy, they're gone.

|Alas, almost unusable under Linux (I'm using shared qt3 build) - the UI is intolerably slow.

|Working great on Fedora 10!

|Surprisingly stable for an Alpha 1 version. Been using it since it came out almost two days ago now, and not a single crash or freeze or problem. Well done!

|go away with this mozilla/ g**gle crap! i using opera since years and i will continue using opera as my standard browser.
Score: 0
|I agree that it's a great browser but making it the default is a bit much, unless it's to prove a point or as a personal quest. I tried for a week, but I guess I was...weak. I mean, it doesn't run silverlight and I've gone to many web pages that just don't render well in the browser (not it's fault, of course). It has a very long way to go before it can ever compete with IE or FF....they're ubiquitous and web designers code for them, that's really all there is to it. But I suppose that's not quite what it's going for anyway.

That's good news to come home to.

|actually it's nonsense to compare opera 10 alpha with firefox 3 (production), you should compare it with development version known as minefield, but these days fork shiretoko (3.1 branch) 3.1b3pre with ACID at 93 and it's much faster than opera 10 alpha.

|For me, Opera's the fastest browser, and features everything I need. Of course there's widgets to it, but Opera mostly got those covered already, without even taking much space ^^
To those of you who claim Opera will be long gone in a while, you wish. Opera's stable, feature-rich and just keeps getting better and faster. Also, every single feature Google Chrome got Opera has too, except for Chrome's privacy mode. Though, I bet we can expect that in not too long.
