The main difference between Firefox and Opera is the perspective of how the user should be catered for. I want a fast web browser, an RSS client, an IRC client, an e-mail client, desktop widgets, and so on, without having to fiddle with dozens of downloads for software installers and extensions and all that other stuff. Most of these features are not enabled by default (RSS is enabled when an RSS link is clicked on, e-mail is enabled when an account is created, IRC is tucked away in the menu, and so on) and take up practically no space on the hard-drive so if you do not have a use for them they are neatly tucked away as if they were never there.

Opera also includes some nice productivity features that most browsers totally neglect. The "speak" function is incredibly helpful when trying to multi-task. One can open an e-mail, select all the text in it, and then click "speak" so Opera will read the e-mail to you and while you are listening you can do other things like work on Word documents, write replies on Neowin, and so on. You've also got a built-in panel for making notes. If you find some particular bit of information you think you'll find helpful later on, you can select the text on a webpage, "Copy to Note", and Opera will not only make a note with that text in it but the note also serves as a bookmark if you double-click on it. Opera's fullscreen mode works in Projection mode so websites can either show themselves normally or they can switch to projector-presentation mode. Thus, if you write an article webpage you can make use of the CSS projection mode to break the information up in chunks in fullscreen mode for use as presentations. Combine this with the fact it is easy to install Opera on a thumb-drive and you've got a portable internet suite, research tool, and presentation device. None of the features in themselves sound awesome but they can incredibly powerful when used together.

These are some of my main reasons for using Opera. One could probably get the same results in Firefox if one is willing to fiddle with extensions, separate applications, and so on but this is too much work and consumes too much space (especially if used on a cheap thumb-drive) to be considered worth-while when one can easily install Opera with this functionality out-of-the-box.

As for standards compliance, I think some people have been confused about the purpose of the Acid2 test. The Acid2 test was created to test the ability of browsers to correctly handle certain features of certain specifications. In no way is the Acid2 test comprehensive. There actually is no such thing as a browser that inerrantly follows all of the standards created by the W3C. All rendering engines, and thus browsers, have their own little quirks and deviations from the W3C standards.

I cannot say whether Opera works with as many sites as Firefox. I haven't actually done any tests. I haven't noticed any problems on the websites I visit though. Opera and Firefox are rather close to eachother in terms of standards compliance so there shouldn't be much deviation between them. Most of the problems I've ever noticed in Opera were incredibly tiny ones -- perhaps an element is 1px over too far in a certain direction -- or ones that you would only find if you were somebody messing with the latest CSS features in an exotic way as part of some experiment that was never intended to work in most browsers. In general browsing, you shouldn't notice much difference between the rendering behavior of Opera and Firefox.

Opera passes the Acid2 test and is 100% XHTML and web standards compliant (which is more than Firefox,) so anything that works properly in Firefox should also work properly in Opera. If it doesn't it's the fault of the webmaster for not using standardized, compliant code.

"Does opera work with the same number of websites that firefox does? Or is it incompatible with lots of websites?"

If You encounter problems with Opera rendering certain sites in vast majority of cases it will not be Opera's fault. In such case press "f12" on keyboard while You are on problematic site and choose "edit site preferences". Here You can pick which browsers will Opera emulate(IE, Firefox..). Use the mask option since by choosing that 95% of those sites will now render properly. Talk about bad site coding ^^, luckily Opera has the answer to that :)

I know that Opera passes the Acid2 test (a good thing) but it's not a comprehensive test for total web standards compliance [1]. Unfortunately, Opera is not 100% XHTML compliant [2] or 100% CSS compliant [3]. Opera is close, however. Right now, there is no such thing as a fully standards compliant web browser.

Some of W3C standards are not 100% clear how a specific feature should work thus making Opera's and Mozilla's implementations a bit different. These things are usually fixed along the way - therefore I must say that we (yes I work for Opera) are 100% W3C compliant. A couple of our guys are sitting in W3C group and working on standards and proposals. When it comes to CSS I have to say that there is no browser that is more CSS compliant than Opera since H?kon Wium Lie, who btw. is inventor of CSS works at Opera Software.

As previously said, unfortunatelly all pages do not work as they should on Opera due to bad coding and UA sniffing. If a page does not work as expected please report it to us with extensive description and how to reproduce (either via Help->Report a site problem or our OpenTheWeb team).

Difference between Opera and Firefox are mainly these:

* Opera exists for virtually every platform, Firefox does not

* Opera uses approximately two-thirds the amount of memory of Firefox

* Opera is optimized for speed and renders pages faster

* Opera Software strives to always have the latest bleeding edge technology built-in the browser (latest additions are canvas, SSE, SVG)

* Built-in tools for web developers

* All W3C standards are followed to 100%

Please remember I'm not a fanboy - just giving you the hard facts.

goodness.. that's pretty good stuff

I'm wondering about RSS in FF compared to Opera, why can't I just get a drop down list of what happend lets say on latest news on BBC while opera just takes me to a page where I have to scroll down to read everything.

Yeah, I love the RSS "Live Bookmark" implementation in Firefox. It's the only way I'll use RSS feeds.

    • Microsoft is making Windows 11's context menus faster, simpler, and configurable

      By tboggs13 · Posted

      Yes, exactly what I have been thinking. Don't make the context menu simpler, make it smarter to learn what I actually use. And then, give me the ability to pin settings that I rarely use but need forget where they are.

    • Here's how to watch Summer Game Fest 2026 and what to expect from the 2-hour showcase

      By LoneWolfSL · Posted

      Here's how to watch Summer Game Fest 2026 and what to expect from the 2-hour showcase by Pulasthi Ariyasinghe The June game showcase schedule is packed, and with the Sony event already behind us, it's time for the next major presentation to come in swinging. Later today, Geoff Keighley will be bringing the 2026 edition of Summer Game Fest live from the Dolby Theatre in Los Angeles, California. For anyone wanting to tune in online, the Summer Game Fest showcase livestream will be kicking off at 2 PM PT | 5 PM ET | 10 PM BST later today, June 5. The jam-packed show is slated to run for about two hours, with platforms like YouTube (4K at 60FPS), Twitch, Facebook, or X being available for catching it. Like in previous years, separate streams featuring American Sign Language and Descriptive Audio are available on YouTube as well. Keighley has only dropped a few teasers about what gaming fans can expect to see at the show. This includes a new look at Star Wars Zero Company from EA, a major announcement from Guild Wars developer ArenaNet, more Clutch gameplay, and some sort of Sega presence. As for fan expectations, there is hype building about a Final Fantasy 7 Remake Part 3 reveal here, and we might see new details about announced games like Alien Isolation 2 as well. If you want even more games, keep in mind that right after the main kickoff event, the Day of the Devs showcase will begin its own festivities at 4 pm PT | 7 pm ET. This is focused entirely on upcoming indie games. Following this, the next major games showcase is slated to happen on June 7. Here, Microsoft is bringing the big guns with its Xbox Games Showcase and Gears of War E-Day Direct. Check out the full calendar for all of the June events over here.

      I think the car analogy is more this: Left hand drive, basic commands on the left side of the infotainment screen. Right hand drive, basic commands on the right side of the infotainment screen. Granted, you're not swapping between the two often so it's doesn't really work. But it's to do with the proximity of you (your mouse, or the driver) to the controls.
