If you didn't notice from reading my last massive time waster, I love classic gaming. I'm also a Firefox user, and always on the hunt for good addons like the rest of you. Thank god for FireNES, an awesome addon for Firefox that gives you ready access to a massive repository of NES games.

After you install it, customize your toolbar and add the FireNES button to give yourself one-click access to the sidebar. The full ROMs list is massive, The toplist contains the 100-or-so most played titles, and you can add any game to your list of favorites with a simple right click.

Best of all, you don't have to hunt down ROMs on horibly cluttered, scam-laden websites. Awesome.

The only possible downside to all this: habla usted español? The developer's page is Spanish only - not a big deal, the install link is easy to find and you can always run it through your favorite translation app.

Since switching to Firefox, there's one Internet Explorer function I've been wanting to duplicate: copying my browsing history when opening a new tab or window. Developer Twanno has created an extension that adds that missing functionality, and another that I find particularly useful.

The Duplicate Tab extension does exactly that, creating a second instance of your selected tab in a new one (or in its own window). It can also perform two other useful functions. First, it will "detach," a tab - close it in your current window and open a new window with the same URL and your browsing history.

Second, you can use it to merge different windows - combining their tabs and history in a single window.

Tab Clicking Options gives you the ability to control your tabs through different mouse click actions. It's compatible with other tab extensions, so I've set mine up to duplicate a tab when I double-click on it. A host of action are supported, including reloading, bookmarking, closing, and even switching to IE view (if you have the extension installed).

These are two great, small extensions for Firefox users looking for more control over their tabs and windows.

Design inspiration can come from a lot of different places. If you find yours from digital sources on the web, Palette Grabber for Firefox might be incredibly useful to you.

Install it, and Palette Grabber sits in the left corner of your status bar waiting to leap into action. A single click (right or left) exports a selective palette based on your current page in Firefox. Palette selection is very intelligent, producing accurate swatch sets for each of the websites I sampled.

Palette Grabber supports several file formats, including Photoshop, Flash, Fireworks, PaintShop Pro, the GIMP, and Mac OS X Color Picker. Minimalists and power users can elect to save a tabbed text listing of RGB values.

For a 25k download, Palette Grabber is definitely worth adding to your Firefox install if you do any digital design work.

If bookmark menus aren't enough for you, All Customized Links offers yet another tweak to speed your Firefox browsing.

A word of warning to privacy fanatics: you must register an account to use this, and your links are remotely hosted (there is no TOS that I could find). While not posting privacy terms isn't cool, your links following you wherever you install this addon is.

Adding new links is a breeze through the preferences menu. Enter a name, url, and choose where you want to open it: current tab, new background or foreground tab or window,

An interesting preview option is included, though it's not so much a preview as it is loading the whole page with it's opacity turned down. I was expecting maybe a pop-out thumbnail of a site, not the exact same thing I'd see if I clicked it's entry. You may want to turn previews off in your preferences, it's just not that useful.

All Customized Links' menu also features a quick option to add the current URL, which will save you a bit of typing over just entering everything from scratch by yourself.

This isn't the kind of addon that's going to revolutionize your browsing experience, but it's a nice option for those looking for additional bookmarking options.

If you happen to buy or sell on eBay frequently, the Lauge custom browser is an interesting tool you'll want to check out.

Lauge sports a ton of functionality that makes using eBay less bothersome. The search tab provides a handy tree view of all eBay categories and makes navigation around the site a snap; favorite your go-to categories to access them quickly later. It also includes a simple keyword search and seller search with results filtering options.

Once you've selected a category to browse, Lauge activates the gallery view which provides a thumbnailed view of all eBay gallery items. It's a great visual tool for separating the wheat from the chaff in a hurry. Item listings can be sorted in the same ways as on eBay's site, and you can fully customize which columns you'd like displayed in the results pane. Some options, like item condition (which would be truly useful) don't yet display, though that may have more to do with sellers not specifying it in the first place.

Lauge also handles tabbed browsing, making it easy to switch back and forth between items or categories. On the downside, the panes aren't resizable which can make the item view a bit cramped. Clicking the orange "eject" button will open a full screen view that remedies the situation and lets you view the item in detail as you would on eBay.

Lauge supports English and German, and requires the MSXML 4 download.
