You can install Opera themes for Firefox to make the Firefox web browser look more like the classic Opera web browser after installation.

Version 3.6 of the Firefox web browser introduces several new design options for theme creators that are not available in previous versions of the Internet browser, including the latest official release version Firefox 3.5.4.

One of the first themes to make use of these new features is the Operetta theme which is available as an experimental theme from the official Mozilla Firefox website.

The Operetta theme comes in two versions: a normal and advanced version. These differ mainly in the toolbar layout. Both Operetta themes are based on the design of the Opera 10 web browser with the normal version making use of the standard toolbar layout with tabs below the other toolbars, and the advanced version placing the tabbar above all other toolbars.

Both editions of the Firefox theme look professionally done and the selection comes down to the personal preference of the user.

Some Firefox design mockups suggest that the developer's are thinking about moving the tabbar to the top of the web browser header and the Operatta Advanced theme for Firefox can be used to get accustomed to this possibility.

It might also be the prime choice for Opera or Google Chrome users as these web browsers place the tabbar by default above most - in Google Chrome's case all - other toolbars. The Operetta and Operetta Advanced themes are available at the Mozilla Firefox website.

Update: The theme is no longer available on the official Firefox themes website. An alternative is the Fopera theme. Here is a screenshot of the theme's header when installed in the Firefox web browser.

Update 2: You can install Opera themes for Firefox to make the Firefox web browser look more like the classic Opera web browser after installation.: The theme has not been updated since 2011, which may be an indication that it is no longer actively maintained by its author. It is unfortunately the only remaining Opera theme for the Firefox Internet browser.

      Like I said, I credit Firefox. I just think that too many people don’t know enough internet history to recognize the credit due Opera for its ongoing leadership in the community.

      It’s also not accurate to say that Opera invented everything great about browsing. It didn’t, and Firefox does offer some innovations of its own, and good ones, too.

      All I was saying was the discussion about what makes Firefox good or Opera not so good should not stop at looking to market share, for the reasons I have already mentioned. Discussing the merits of the browsers is worthwhile, but market share is what GM had and that does not necessarily inspire.

    Hey MikeJ,

    Don’t confuse “market share” with “quality” – the two are not synonymous. Surely you don’t think McDonald’s food is the best food in the world just because it has more restaurant locations than any other chain? And again, just because Porsche sells less cars than Mazda, does that mean necessarily that a Mazda is a better car?

    There are several interesting reasons why Opera consistently flies below the radar, and none of them have to do with its quality. At the very least, if you look at the history of web browsing, you’ll find that most of the features that are very cool today were Opera innovations (mouse gestures, speed dial, easy page text sizing and of course, true multi-threading tabbed browsing – try cascading windows within Firefox).

    I will admit that, ultimately, I use Firefox more, simply because it is simple. Opera requires some techy inclinations that the average user won’t have. All credit to Mozilla for seizing on the simplicity and stability that users want.

    However, do recognize that most of the issues with Opera functionality is a result of a well-documented battle it had with Microsoft and how code is written to make it easier for some browsers and…not so easy for others.

    In truth and fact, Opera is a champion for the values netizens really appreciate, an innovator whose work from desktops to mobile apps has made life easier for all of us, even those who use other browsers built on the innovations Opera introduced. Market share or no, they should get their just respects.

    Obvioiusly, you can tell that I’m not a fan of MSIE, but then, most who would post to this board wouldn’t be and, in my opinion, rightly so.

    Oops. I mistaken that for Opera 9.0 design. I dislike Opera design newer that 9.0.

    Firefox Noia theme is pretty good for me.

    I switched to FF after using Opera for 7 years, and I won’t return back. Now Opera is just my spare browser.

    It seems that my wife will convert totally to FF too: some .js menus don’t work in Opera, and she gets Opera infamous “100% CPU usage” error frequently.

    All you Firefox fans… admit it finally: Opera is actually better, can’t see any other reason why Firefox would copy so much things from Opera ..:)

      As I have mentioned, I have given Opera a serious try 3 or 4 times but always go back to Ff. There has to be a reason why this “superior” browser hangs in consistently at about 2% of market share.

      If Iron had the add-on’s Firefox has, though, it would quickly become my default.
