Top Firefox Extensions

As we all know. looking for the best Firefox extensions in Official Firefox Add-ons is like searching for  the proverbial needle in a haystack.

I am a Firefox extensions addict and I try a lot of extensions every week. You can see my periodic new extensions in the Firefox Extension Picks series that I feature once in every few weeks.

I uninstall the ones that I don’t like or need and the ones that stick around in my browser make it to this list.

History of this list

I put together this list when I wanted to share these wonderful extensions to my friends new to Firefox. As well as this serves as my own reference when I am setting up a new Firefox browser or for some reason restore my own browser from scratch, this is the list I refer to get my Firefox extension fix. And I hope it will be yours too.

What started as a list of a dozen add-ons is now the most visited page in ShanKri-la featuring 65+ awesome Firefox add-ons. I keep it updated as and when I find the best of the best of Firefox extensions.

Firefox Tips

Here are a few tips for a fun Firefox browsing experience

  • It’s always a good idea to backup your profile, extensions, etc. with FEBE before you try a new extension. Some extensions don’t play well together. (Use FEBE see below)
  • If your Firefox seems very slow, it could be because you are using a lot of extensions.
  • Remember the Profile Manager option. In Windows, start Firefox from command prompt: firefox.exe -profilemanager
  • Power users can alleviate the overuse of extensions by creating different profiles. I switch between profiles for casual browsing and web development which keeps my Firefox lean and mean.

What type of extensions are you looking for?

I have the created the following categories based on the type of extensions you might be looking for.

  • Starter Pack – If you are just trying out Firefox, here are a few extensions that will introduce you to the power of Firefox.
  • Power User Pack – Aimed at the power users who aren’t afraid of getting their hands dirty and who want to squeeze every bit of power from their favorite browser.
  • Usability – Aimed at improving browser usability by modifying Firefox chrome or the built-in features.
  • Productivity – Extensions aimed at improving Productivity while you use the web for your work
  • Fun – When you turn to the web to have some fun.
  • Blogging – Useful for bloggers. Look at the add-ons and you’ll know what I mean.
  • Social Media – Not all bloggers use all Social Media s this category zeroes in on just the Social Media extensions.
  • Web Developer – Aimed at techie’s like myself who either run a website or do some web development.

Starter Pack

If you are just trying out Firefox, here are a few extensions that will introduce you to the power of Firefox.

  • Adblock Plus – Ever been annoyed by all those ads and banners on the internet that
    often take longer to download than everything else on the page? Install Adblock Plus now and get rid of them.
  • Adblock Filterset.G Updater – This is a companion extension to Adblock or Adblock Plus and should be used in conjunction with it. This extension automatically downloads the latest version of Filterset.G every 4-7 days.
  • ForecastBar Enhanced – Mod of the popular ForecastFox that shows weather information in your status bar. This one features enhanced animated radar map as well and I love it!
  • TabMixPlus – Tab Mix Plus enhances Firefox’s tab browsing capabilities. It includes such features as duplicating tabs, controlling tab focus, tab clicking options, undo closed tabs and windows, plus much more.

Power User Pack

Aimed at the power users who aren’t afraid of getting their hands dirty and who want to squeeze every bit of power from their favorite browser.

  • CLEO package – CLEO is (Compact Library Extension Oraganizer) an extension that helps you create your own extension package (as a .xpi file) from your favaorite extensions (backed up using FEBE). When you want to move your extensions to another computer or three, just copy the custom xpi package you created and open it. Voila! You have cloned your Firefox extensions..
  • Firefox Environment Backup Extension (FEBE) – Schedule and automatically back up everything about Firefox.. bookmarks, profiles, saved passwords, form history, etc. No more fear of re-installing Firefox or breaking it with a new extension. You can even upload your backups to your account.
  • Foxmarks Bookmarks Synchronizer – Use Firefox on multiple computers? Install this extension, create a Foxmarks account an forget about keeping your bookmarks in sync. Foxmarks will do it for you.
  • Greasemonkey – Allows you to customize the way a webpage displays using small bits of JavaScript. Ex. some of the best Google Greasemonkey scripts for Gmail and Google Reader should get you started on your way to becoming a Greasemonkey script addict!
  • OpenSearchFox – Add any website’s search box to your Firefox search bar by right clicking in the searhch box in a website! It doesn’t appear in the Firefox add-ons site anymore but this link takes you to the download page and it works great even in Forefox 3.0.1.
  • Menu Editor – TinyMenu mentioned in the next section helps save real estate but it increases the number of clicks to get to your menu option. Menu Editor lets you completely customize your menus. Hide and rearrange options you don’t need making your Firefox menus work for you.
  • Remove it Permanently (RIP) – Permanently hide content from web pages using the context menu. Very powerful to customeze your web experience. A powerful options panel that lets you fine tune your preferences to your liking.
  • SecureLogin – It uses the Firefox’s built in password manager and disables automatic pre-filling. It highlights the form fields if it detects a saved password and with a customized click or a keyboard shortcut, it fills the username/password as well as signs you in, in one short step. Very useful! I, however, recommend using a more powerful password manager such as Passpack.
  • Stylish – Stylish is for CSS where Greasemonkey is for Javascript. Completely customize the looks of websites with Stylish scripts. Browse to find the ones you like. One of the popular example is Re-Designed Gmail Stylish script.
  • Update Notifier – If you can’t wait to know when a Forefox extension has been updated so you can upgrade it right now. Also, provides a useful ‘Restart Firefox’ option in its menu to restart with one click.
  • Site Launcher – An experimental add-on thats a must-have for thos who love keyoard shortcuts. Just think Launchy for Firefox. You can launch your favorite sites with just a few hotkeys. Read the full Site Launcher review here.

Usability Add-ons

Aimed at improving browser usability by modifying Firefox chrome or the built-in features.

  • Back to Top – Back to Top helps navigate long pages. Go to the top or bottom of a page with a single click. Using right clicks and control clicks you can scroll a page or line at a time.
  • Download Statusbar – Download and view status of downloads in a tidy statusbar. No more annoying download window blocking your browsing experience. A full view as well as a tiny view for screen real estate usage.

  • HashColoredTabs+ – Adds a colored favicon square for those sites without a favicon. This helps you identify tab contents based on a distinct visual cue.

  • FireGestures – Allows you to execute common commands (like page forward/backward, close tab, new tab) by mouse gestures drawn over the current webpage, without reaching for the toolbar or the keyboard…

It adds a little edit button to the box and on clicking will take you to your favorite editor and on saving will transfer the content over to the box in the web page. Very handy.
  • Smart Bookmarks Bar – Do you customize your menu bar to save screen real estate? Now you can hide your bookmark names in the toolbar and show just the favicon saving a lot of space. On mouse over, you’ll see the name of the bookmark for those without a favicon.

    Great site, thank you. I have not browsed through the new options in firefox 3.6 yet so I am not sure if they added the addon as an option, but I am surprised not to see the homepage addon for new tabs listed here. It has to be the most usable addon available. None the less, great site, I will check back often for more addons.
