Where do you get your fix of fun, interesting sites to look at? These days, it's probably Reddit, Twitter or Facebook. But do you remember the time when the best site to find new interesting content was StumbleUpon? You might be pleased to know that it never really went away. People have continued to Stumble cool content all this time, so with a few tweaks it's now actually better than ever.

StumbleUpon is making a bit of a resurgence recently with a brand new web interface and new mobile apps to play with. So, maybe it's time we take a look at the easiest way to fuel your Stumble-addiction: The good old Firefox extension.

Get StumbleUpon For Firefox & Customise Appearance

Download the Firefox StumbleUpon extension from the Firefox directory [No Longer Available] or from the StumbleUpon downloads page. While you're there, it's probably a fun idea to grab the bookmarklet too. Just drag it to your bookmarks toolbar. To keep track of your favourite sites and your friends, you will need to get an account with StumbleUpon.

The first thing you're going to want to do is customise your set-up. Personally, I don't have the patience for a whole toolbar dedicated to StumbleUpon, so I like to have it pop-out when I'm using it. It's also possible to fully customise exactly which icons appear on the toolbar and in which order. Plus, you can nominate whether to pre-fetch sites or not in order to make things quicker when Stumbling.

To change your preferences, head to Tools > Add-Ons and click on "Preferences" for StumbleUpon. To set up a toggle button for the StumbleUpon toolbar, ensure "Show Toggle Button" is checked. You may need to reload Firefox to see the button. Then choose "Drag to Position" in order to choose your positioning of the button and choose from the drop-down menu where you'd like the bulk of StumbleUpon tools to appear.

Next, get stuck into choosing exactly which controls and modes you want to show up in Firefox. Maybe you want to be able to tag things in StumbleUpon, or share with friends on Facebook - or maybe you have no use for that. Clean things up so that you only see exactly what you need.

Choose Your StumbleUpon Topics & Modes

Head to the StumbleUpon toolbar and click the drop-down menu that says "All". At the bottom there's an option to "Update Topics", which will take you to the web interface and recommend topics to you.

Once you've chosen a few topics, these should be reflected in the same drop-down menu within Firefox. To use them, simply choose the topic you want to see, then Stumble away. Your Stumbling will be from within that topic until you change it back to "All" or choose a new topic. This is a great way to stick to what interests you at any given moment.

The other items at the top of this menu are the various modes you can use. For instance, you can choose "Following" and get only websites that the people you follow have liked. You can also limit your results to just "Video" or "Photos", among other things. There are also more modes for popular websites, like Wikipedia and Scientific American. The point is, you should be able to limit your Stumbling to just things you're in the mood for. And that's important!

StumbleUpon For Firefox Search & Bookmarking

Within the StumbleUpon preferences, there's a "Search & Tagging" tab. Here, you can decide whether or not you'd like StumbleUpon to give you more information about search results within Firefox, such as whether your friends liked the page or not.

You can also decide to get the StumbleUpon extension to automatically bookmark and tag your favourite StumbleUpon pages as you go, which could save you a lot of time.

More Configuration

On the "Configuration" tab of the preferences, you can set automatic Stumble-after ratings for pages you didn't manually like or dislike. The "Shortcuts" tab will let you set keyboard shortcuts for your favourite StumbleUpon functions, such as Stumbling and rating pages.

More Coming

The new tools unveiled in the Beta web release include lists and other interesting ways to arrange content. No doubt these will soon also be reflected in the Firefox extension as a new mode.

Are you going to give StumbleUpon another go?
