No Web browser is perfect, and there are several things about the interface of our favorite browser that we'd like to change. These 20 free add-ons (listed in alphabetical order) tweak your Web browser's interface in many different ways, allowing you to customize several appearance and functionality components.
2009 Holiday Boom Pack
The 2009 Holiday Boom Pack provides you with several different themes and skins related to various holidays. These include New Year's Day, Valentine's Day, and St. Patrick's Day. You are given the ability to switch between "Booms" quickly via the add-on's integrated drop-down menu and you can also download new holiday content as it is released.
All-in-One Sidebar
All-in-One Sidebar turns your sidebar into a centralized hub for some of the browser's main features. These include your add-on control panel, download manager, source code viewer, bookmarks, history, as well as detailed site information.
Chromifox
Chromifox applies a blue theme to your browser similar to that of Google Chrome, which was initially based off of the open source Chromium.
ColorfulTabs
ColorfulTabs displays each open tab in a different color. The coloring scheme can be set to randomize, use a default palette, or generate based on domain name.
FireGestures
FireGestures adds customizable mouse gestures to your browser. Mouse gestures allow you to perform both basic and advanced functions in Firefox by utilizing a series of mouse movements and clicks.
Fission
Fission incorporates the browser's progress bar with its address bar, similar to the display in Apple's Safari browser. The progress of loading a webpage is noted by a dynamic colored bar that is shown behind the current page's URL.
FoxSaver
Digital picture frames have become all the rage, and the FoxSaver extension transforms your browser into one that pulls photos from a compendium of thousands as well as from your own personal collection.
Greasemonkey
Greasemonkey allows you to modify the way web pages display by utilizing JavaScript code. Thousands of unique scripts tailored to a large number of sites are available free of charge.
History Submenus
History Submenus enhances the browser's default History menu by displaying each respective day's full browsing record in its own sub-menu. While Firefox normally displays the last ten sites visited on a particular day, this extension expands that functionality by displaying each and every recorded page.
