Comparing Firefox 3 With Opera 9.5 On Linux 489

Joe Barr writes "Mayank Sharma has two recent stories on Linux.com; one evaluating the performance of Firefox 3, and the second comparing it to Opera 9.5. Which is better? For most people, it's probably more a matter of familiarity or personal preference, but these stories provide hard performance data to consider as well. Sharma notes, 'In terms of rendering JavaScript, Firefox 3 had the edge over Opera 9.5 in the SunSpider JavaScript Benchmark, which has an error range between +/-0.8% to +/-11.3% depending on the type of test. In the JavScript Engine speed test, Opera 9.5 scores over its peers when it comes to error handling, DOM, and AJAX.'" Slashdot shares a corporate overlord with Linux.com.

    The real challenge/merit is whether Opera 9.5 is accepted by webpages as being able to display all the content correctly, rather than insisting a component isn't there and demanding its download only to be told it's still not there.

    That's my complaint about the last version or two of Opera (and I've been using it since 3.5), that I wind up having to break out IE or FF for some pages because just being adherent to the HTML 4 standard isn't enough of a claim anymore.

    The first thing you notice when you launch Opera 9.5 is that it occupies less desktop real estate than Firefox 3, with less toolbar space and smaller borders, giving you more room to view pages.

      Opera's interface is every bit as customisable if not more so. Right click on any toolbar and click "Customize." The "Toolbars" tab will let you play with which toolbars you want to show, and where you want them. The "Buttons" tab will allow you to place just about any button anywhere you want. Finally, you can even make your own buttons. See the Opera wiki for more information: http://operawiki.info/CustomButtons [operawiki.info]

        False. I challenge you to put a "back" button next to the Help menu on the menu bar, then. You can do it in IE. You can do it in Firefox. Opera forces that space after Help to be waste.

          Here it is:Screenshot [imagevenue.com] :P

          There's a back button, forward button and an addressbar next to help. Not technically what you said but close enough that it shouldn't matter. Probably technically cheating aswell as it's not the 'real' menu bar.

          You're right that you can't put stuff in the menu bar in Opera though, and you should be able to. It is a waste of screen space. In order to make that screenshot (without manipulation), I used the custom buttons page on http://operawiki.info/CustomButtons [operawiki.info] to add each of those menu items to the "Main Bar" (after clearing it), then I added the back button and decided to go a step further and add the address bar and forward. I had already used the toggle menu bar custom button to hide the actual "Menu Bar" (I normally don't have a menu bar even, the panel is enough).

          If you look closely I have the entire main menu as a button in the tab bar (labeled "Menu" with a black arrow next to it). If I click that I'll get a menu with all the main menu bar items in it. Over on the right I have a view button which will display the "view bar" where I've hidden the menu toggle button.

          I could have combined everything on the menu into the tab bar instead but it wouldn't have looked like the main menu colorwise. I could have everything in one bar like the great-grandparent has in their firefox screenshot. Less than their screenshot even if I put everything in the tab bar instead of a seperate one.

          Also there is a panel toggle on the left of the screen. I typically don't use the main menu except for the File-> Import/Export menu options so hiding the entire thing makes sense since all bookmarks, history, widgets, mail and newsfeeds are available in the side panel and most settings are accessible via keyboard the shortcuts F12+none, ctrl, shift.

          If you really want to get bitchy about wasted space you could put all the menu options, the addressbar and everything normally in a toolbar into a custom panel and get rid of every bar (even the tab bar if you want) and just have the panel toggle at the edge of the screen. Hide it when you don't need it. You can't get much less wasted space unless you changed the theme for your desktop to use less space for the window decorations (I think that would be going a little far). The entire window would be space for the page except for the small scrollbar on one side and the panel toggle on the other (not necessary with keyboard shortcuts).

      You can set up Opera that way, but it involves a lot of obscure setting-tweaking for the menu-bar-on-one-line effect.

      So I have to grant a small point to Firefox for UI configurability. I still prefer Opera's look overall, though.

    I gave Opera 9.5 a whirl last week and was highly impressed. It's packed with nice features (Where do you think Firefox and IE get most of their ideas?) but still pretty fast and light. Other versions of Opera never did much for me, but this is the first proprietary application that I've run across in a long time that I would seriously consider using on a daily basis.

    In Firefox, my priority is not speed. I am happy with the status quo. While I love the new product, I was dismayed and disappointed to say the least when I was locked out of my favorite sites which support the Firefox 2.0 series, but do not support Firefox 3.0! I had to re-install the earlier version, which I had to "dig" out of the Mozilla site.

    The fact that most of my extensions are un-installable in the latest version did not help matters.

    This made me wonder...Why haven't the coders ported these extensions to Firefox 3.0 if it has been in development for a long time?

      Why haven't the coders ported these extensions to Firefox 3.0 if it has been in development for a long time?

      That's an elephant in the room that nobody seems to want to talk about. If you are praising extensions, then apparently it's a huge advantage Firefox has over other browsers, but if you are complaining about extensions, then they are all third-party developers that have nothing to do with Firefox. It's a win-win for Mozilla - all of the credit, none of the blame.

      This is never more apparent than when a new major version of Firefox is released. Mozilla break compatibility and wash their hands of the mess, and if the extensions you use aren't maintained any more, then, well, tough.

  • I didn't see anything about the one JavaScript feature I use more than anything else in Firefox: the ability to turn it off selectively (via the noScript extension, so one could argue that it isn't in Firefox at all, of course). Useful as JavaScript is, the way it is used to sneak adverts and other unwanted stuff on to your browser can sometimes make a website useless - at least to me.

    I wouldn't be on the Web at all without it. I wonder how many depend on it the same way.

  • I run both Opera and FireFox however Opera never FEELS faster to me. Perhaps it is the default settings, or perhaps the sites I go to Gmail, Gcal, Slashdot, etc, all feel a lot faster in FireFox.

    Also, FireFox feels easier to use.

    And then, FireFox has all of the plugins I now love, and can't get rid of.

    I've been an Opera fan since they took out the ads. Anyways Opera 9.5 with flash on linux plays youtube videos somewhat stuttery and if a tab with a flash video is left open for a few hours the browser mem leaks and begins hogging all the CPU. I'm pretty disappointed because before this Opera has never mem leaked, never crashed, it was an extremely stable browser. One time I accidentally opened 100+ tabs simultaneously, and it did fine.

    And yes I will be filing a bug report.
