The features to love here are plentiful. You can dynamically, show bookmarks by using folder and search terms.  Highlight the bookmarks in any color you would like, sort the bookmarks by name, visit time, last visited and most visited, and a lot more.

Incredible Bookmarks also help you clean house.  It can:

• Run a check to find out duplicate bookmarks in each Incredible Bookmarks toolbar.
• Run a check to check the links in each Incredible Bookmarks toolbar to see which links are no longer available.

This video covers some more of the basics when it comes to using the Incredible Bookmarks add-on for Firefox:

This add-on for Firefox has incredible promise, and I could not find a feature I didn’t like.  My favorite overall feature is the ability to color code your bookmarks and bookmark folders.  I like to keep things neat, nice and organized – so this suits my needs, perfectly.

To learn more about Incredible Bookmarks, check out the official site, and you can download it from the Firefox Add-ons web site.

Did you know you can tidy Firefox up, with VACUUM? No, I do not mean that thing you use to clean your carpets.  Here is a way to VACUUM your places database from within the browser.

Here are the steps you need to take:

1. Open the Firefox tools menu and click on error console.
2. Paste the following command into the code box as a single line:
Components.classes["@mozilla.org/browser/nav-history-service;1"].getService(Components.interfaces.nsPIPlacesDatabase).DBConnection.executeSimpleSQL("VACUUM");
3. Hit the “Enter” key or click the evaluate button.

The user interface will freeze for a moment, but after you are done, your SQLite databases should be less fragmented than before, leading to a leaner and meaner Firefox browsing experience.

Thanks goes to Mozilla developer Jeremy Orem for this fantastic tip!

Bonus – Vacuum Places Improved is an add-on that will do this for you automatically.

How can you remove your unused search engines?  Click on the Firefox search box, and then go down and select the Manage Search Engines… option. Now, on the Manage Search Engine List you can move up, move down or remove search engines you don’t use anymore.  

Just because you CAN add 200 or more search engines doesn’t mean you should.  This is just one more quick way you can lighten the load on your favorite browser.

Get More Toolbar Space in Firefox

I think I have a pretty optimized Firefox setup. Personally I don’t think anybody needs more than two toolbars in Firefox at all times. How can you cut down on the clutter and keep everything accessible with just a few clicks here and there?

Clean Up Your Right-Click Menu

From the creator of Colorful Tabs, we have yet another handy and helpful Firefox extension.  FfChrome, for Firefox, is an add-on that trims and slims your context menus.  After installing too many add-ons, your right click menu might get a little cluttered.  FfChrome is here to clean things up.

Clear the Clutter from Your Status Bar

Messy status bars make for bad browsing. Ok, maybe that is not true. They do make for a temperamental and somewhat anal Firefox guru though. Mike wants to know if there is a better way to organize the status bar in Firefox.

Hide Your Menu Bar

Now when it comes to using a browser, some people like a lot of open space and others like to have a plethora of tool bars. Personally I find myself in the first camp – most of the time. That is why I was happy to see this new Hide Menubar extension roll my way.

Compact Your Menu Bar Even More in Firefox

One add-on I keep adding on is Tiny Menu, due to the fact that I like to have a minimalist browsing experience.  However, I have found one extension that does an even better job than Tiny Menu at compacting the standard menu bar down to one small popup menu, Compact Menu 2.

(Bonus) More Ways to Shrink Down Your Menu Bar

Is your menu bar taking up too much wasted space? Well you could hide it, shrink it, or just not use it. How can you get that done? Thankfully others have run into this same issue before and there are a slew of Firefox extensions to help you minimize your Firefox menus.

Have another method that works better for you?  Feel free to share in the comments!

Whitehart – I never did use this theme until I was looking for a simple one for my Kubuntu install of Firefox on my laptop.  Haven’t looked back since!  Very sleek, light and simple.

Chromiefox – Now I am not usually a big fan of the knock-off themes, but I do have to say the Google Chrome interface is pretty nice.  Bring it to Firefox with this download.

Qute – An old one, but still a good one.  Qute is simple and unobtrusive with clear, colorful icons.

Aero Silver Fox – Silver counts as a light color, right?  Just like it’s cousin on our darkest popular themes list (Aero Fox) this theme deserves a spot too.

iFox Graphite – When coming up with this list, I made myself a promise before I started – only include one Mac-looking theme.  All Apple inspired themes are light, so here is the one I picked.

Full Flat – This may be the lightest and simplest theme out there for Firefox today.  Full Flat keeps it simple, but if you enjoy minimalistic and flat browsing, here you go.

hmmXP – Based on the hmmXP theme for Windows by Fugacious, hmmXP for Firefox 3 uses simple, flat and small icons, and does away with gradients and rounded corners.

Elementary Theme – Yes, elementary my dear Firefox fan boy.  This theme is the official theme for Firefox of the Elementary Project.  Simple, light and doesn’t get in the way.

iPox – There is no doubt that iPox is an easy on the eyes, white and blue theme for Firefox.  One of the best examples of creativity and originality by far.

Naver – If you can use green and make a simple theme, you are my new best friend.  A new theme on the block, Naver ads just a hint of color and then keeps the rest pretty simple.

Which theme from the light side is your favorite?  Why do we love or hate the lighter themes out there today?  Let me know what you think.  Also don’t forget to check out the darkest popular themes for Firefox too.

It shrinks your bookmarks down to only the favicons.  So what?  Well, the magic happens when you hover over one of the bookmarks.  Bookmark names will be displayed when you mouse over them.  Pretty nifty, right?

You can pick up the Smart Bookmarks Bar on the Firefox Add-ons web site.

Now with a name like that, I bet you can’t guess what it does. If you said, “downloads kewl wallpaper” I’m afraid you have not won. This extension allows for you to easily hide the menu bar inside of Firefox. This gives you more room to browse the Web. You can always bring it back though, just by hitting the ALT key to show it temporarily.

Icons from the Tango Desktop Project. It is a variant of the “Tango” theme for use with Novell’s Industrial look, see more details there.

Looks pretty good to me, but don’t take my word for it – try it out for yourself.

I have been using it on my notebook PC for a while now, and I can not say I have any real complaints. A lot of the icons and navigation of it look much like the standard themes you see out there. It might not re-invent the wheel, but it is easy on the eyes.

Give it a shot and let me know your own thoughts on it.

Firefox is a truly amazing browser and I think my favorite part about it is that the extensions make it remarkably useful. They add features that I wouldn’t expect a Web browser to do, such as serve as an FTP client. While I think extensions are great, I also find myself installing some that I just don’t need. It is almost like an addiction, and with a new year right around the corner I thought it was a good time to trim some of the “fat” (a.k.a. extensions) off of my Firefox profile by re-evaluating my need for the extensions.

They cover just about everything. From cleaning up your toolbar to clearing the mess from your profile, you have no excuse not to do a little house cleaning before the new year rolls around.
