An internal Opera build passes Acid 3

, ,

Check out this post entitled "Opera and the Acid3 Test" at the Opera Desktop Team Blog.

It will surely take a (long?) while for this to enter into a stable version, but it's already an impressive display of the developers' talent.

Congratulation to Lars Erik Bolstad and the Core Technology Team! :yes: :cheers:

Browser comparison at CyberNet

, ,

Ryan at CyberNet News published the results of his Windows browsers comparison, which includes both beta and stable versions of the four biggies: Internet Explorer (versions 7 and 8 Beta), Firefox (versions 2.0.0.12 and 3 Beta 4), Opera (versions 9.26 and 9.5.9841 beta ("Kestrel")) and Safari (version 3.1).

He tested Javascript performance, page loading speed, and memory usage. The results found good to excellent performance both for the stable Opera 9.26 version and especially for the 9.5 beta, but the competition is fierce from Safari and the Firefox beta.

For javascript, the Opera 9.5 beta came in second after Safari 3.1 and 9.24 was fourth behind the Firefox 3 beta. The last to cross the finish line--and long after the others were home in bed--were the Internet Explorer versions.

For the first page-loading speed test, done on the official Google blog, Opera 9.5 was the winner, beating out Safari 3.1 in second place and again 9.26 was fourth behind the Firefox beta. In the second speed test done on the Yahoo! Search blog, Opera 9.5 and 9.26 were respectively second and third behind the winner Safari. IE7 managed to finish 7th in front of Firefox 2 in the first speed test, but IE8 was last in both.

As for memory use, the surprise winner was the Firefox beta, using globally between 21.3MB and 124.7MB according to how many pages were open and for how long. The Opera versions were "middle of the pack", let's say. The Stable version of Opera was indeed better than the stable version of Firefox, but the beta version of Opera was behind the Firefox beta in all but startup memory use. Looking more closely at startup memory, the IE versions were, of course, the winners there, and the loser was Safari; surprising considering its excellent results elsewhere. The IE versions were however the worst for in-use memory usage (with multiple sites open).

The results of Ryan's tests seem to suggest that there is indeed a new player in town, and his name is Safari (despite a rather rough start). The difference in Javascript performance and page loading speed are pretty insignificant between Safari 3.1 and Kestrel (not to mention the significant improvements for the Firefox beta), but the Opera development teams are definitely going to need to start thinking of Safari as serious competition in the Windows environment (I'm sure they already are).

Yes, to summarize, the Windows browser performance wars are now a three-way battle between Safari, Opera and Firefox. Internet Explorer seems to be KO for the moment, its only advantage being its ubiquitousness.

It would be interesting to revisit these results once the various betas are all officially released. Indeed, testing beta performance is a bit like tasting a cake while it's still in the oven. In particular, I think one should not jump to conclusions concerning IE8's poor performance in Ryan's tests, as it is the least mature of the betas. But what is sure is that the folks at Microsoft need a lot of Gatorade if they expect to catch up with the others concerning performance.

Opera tips and tricks: Ctrl+Alt+Z: A "better mousetrap" for re-opening closed tabs

, ,

This is a tips and trick for Opera versions 9.2x. In version 9.5 re-opening closed tabs is done with Ctrl+Shift+T (unless you've activated 9.2 style keyboard shortcuts.)

A forum post entitled "2 old bugs" attracted my attention this morning. One of the "bugs" in question was indeed something that's been bothering me for a while as well.

The problem:

You probably know already that the keyboard shortcut "Ctrl+Z" will re-open a tab that you (usually accidentally) closed. However, this may not work when there is only a single tab (web page) open. This is the case for me: If I accidentally close a single page, my Speeddial appears and Ctrl+Z will no longer open the previous page.

Bpm took the time to look at this problem closely and found the problem.

What's happening is this: When you close that last webpage, Opera sends you to a "blank" page (or an "empty tab" if you prefer). According to your setup, this may bring up the Speeddial, but the Speeddial is a blank page from Opera's point of view. Because the page is blank, Opera activates the address field (you'll see the cursor blinking there). You can think of the address field as a type of text box. When you're in a text box, Opera presumes that you will want your keyboard shortcuts to affect the text your typing and not the browser as a whole; it can't do both at once. For example, as I'm typing this blog entry, Ctrl+Z undoes what I just typed, but if I click outside of the text box, Ctrl+Z opens the last page that I closed.

So two things are now together: 1) you're on a blank page, so it's impossible to "activate" it, and 2) Opera has moved you to the address field, but you haven't yet typed anything. Result: Ctrl+Z does nothing.

(For that matter, this can also happen when multiple tabs are open. If you close a tab, Opera sends you, by default, to the previously active tab. If by chance that tab has its address bar or some other text box active, you'll have the same problem: Ctrl+Z will affect the text field and not re-open the just-closed tab.)

The solution:

As bpm pointed out: the fact that Ctrl+Z can re-open closed tabs in certain circumstances is just an extra that comes from it's nature: "I, Ctrl+Z, undo that last thing that was done, according to where I am." For the situation described above, Ctrl+Z finds itself in a conundrum: "here where I am, there is nothing to undo."

So how do we resolve this?

Simple.

Use the keyboard shortcut that was meant all along to re-open closed tabs: Ctrl+Alt+Z

Yep, it's been there forever and I had never noticed. Click your trash can and you'll see this shortcut next to the last-closed webpage that's listed there. This shortcut will re-open the last-closed webpage (and then the next-to-last-closed page, etc.) whatever the circumstances may be.

And then finally, think of Ctrl+Z as a 'text-oriented' keyboard shortcut, like in Word, just to avoid confusion.

A big thanks to bpm! :cheers:

Opera tips and tricks: Put unused toolbars to work for temporary storage

Although they're delivered with default setups, Opera's toolbars are designed to be just "holders" within which you have almost total liberty to do as you please.

Why not use this liberty to better organize temporary bookmarks? Here's how...

Opera tips and tricks: Create favicons for your personal bar bookmarks that don't have one

, , ,

Favicons are the little itty-bitty images that appear on the tab, in the address bar and in your bookmarks to visually identify a website. Sometimes however, a website won't have a favicon. Generally, "on s'en fout un peu" as the French would say (we'll translate with "yeah, so?"), but if, for example, you use only images on your personal bar, the lack of a favicon can be aggravating because in this case Opera's generic bookmark icon will be used, and, well, that just doesn't help much to tell you where you're going to go if you click on it.

If you got a little time on your hands, here's how you can fix that.

Opera tips and tricks: Activating the integrated search feature

, , ,

By default in Opera, Ctrl+F will open the "Find" dialog, as in any program, with which you can search the text of a webpage. This Find dialog gives you the most control over your search but it can be clumsy to use. If you would prefer a less combersome interface, while maintaining a certain efficiency in text searching you can use "Integrated Search".
