How to get rid of Australis in Firefox

Few days ago, I wrote about an extension for Mozilla Firefox which will allow you to disable Australis, the new user experience in Firefox and get back the classic user interface. Today, I am happy to share with you that the extension has got a name, Classic Theme Restorer. This awesome extension works like a charm and allows you to get rid of Australis completely, right after install. As the author promised, the extension is available for download in time as Australis reached the nightly build of Firefox.

How to disable Australis in Firefox and get back the classic interface

Starting next year, on in March 2014, Mozilla is planning to bring the Australis user interface for all Firefox users with version 28 of the browser. While the Australis experience has an attractive look and a unified appearance on all supported platforms, it will reduce many customization features available in Firefox at this moment. For example, tabs will stick to the top and you will not be able to change their location. You will be unable to re-arrange buttons and the addons toolbar will also be gone. With Australis, the appearance of the Firefox browser will be more like Google Chrome's UI.


If you prefer the classic user interface over the new Australis appearance, let's see how to disable Australis in Firefox.

How to show tabs on multiple rows in Mozilla Firefox

Personally I prefer to use Mozilla Firefox web browser at work and at home. I switched to Firefox when the Opera browser switched to using Google Chrome's "Blink" engine. I missed the flexibility and speed of classic Opera in the new version and so I switched to Firefox. I found that flexibility in Firefox, and so now, it is my primary web browser.

I work on the web daily and very intensively. As a result of my activity, usually I have a number of tabs open in the browser at any moment. The default Firefox layout has all the tabs placed on a single row. This is not flexible enough for power users like me. So I decided to try to make the tabs spread across multiple rows. This reduces clutter on one row and is very useful for me. Follow the instructions below to make your Firefox browser show tabs on multiple rows.

How to disable JavaScript in Firefox 23 and above

The Mozilla team, which develops the popular Firefox browser, introduced new simplified browser settings with the release of version 23.  One of the settings which disappeared from the user interface is the one to control JavaScript. In previous versions of the browser, you were able to enable or disable JavaScript with a simple checkbox. But, starting with version 23, Firefox does not have it any more. Mozilla claims that most modern websites are unusable without JavaScript.

Today we will look at why you might want to disable JavaScript in Firefox and how you do it.

Firefox 19 comes with a built-in PDF viewer. It looks like this:

Although I like this new feature, because it works fast and looks smooth, you might want to disable it for whatever reason (for example, if the full PDF is not rendered perfectly) . Read below to see how.
