Anyone who reads this blog knows I like browsers, a lot. Features are really important for any browser, but what turns an ordinary program into a feature-filled powerhouse are its add-ons. I've always loved Firefox for this very reason.
Add-ons are something everyone should be using, so I'd like to share what I consider to be the best ones.
Here are my current add-ons for Firefox, in alphabetical order.
Adblock Plus
I know I really shouldn't be advocating the use of this add-on. By viewing websites without loading their advertisements, I'm hurting the very sites that I enjoy. But in all honesty, the practicality and convenience of this add-on outweigh any moral qualms I have about using it. It blocks almost every advertisement on every website, keeps an auto-updated list of URLs t block, and even works on YouTube ads. It's improved a lot since I first used it, and I almost never encounter an ad these days.
Delicious Bookmarks
I'm a long-time Delicious user, and now that its fate is no longer in jeopardy, you should become one. It's a public, synchronized, and social way to bookmark sites. It's a really great way to save important sites and discovering new ones. There really are hundreds of other uses for Delicious, and the Firefox add-on integrates it really well with your browser.
Download Statusbar
Annoyed that Firefox's download window opens every time you download something, interrupting you in the process? Install this add-on for a Chrome-like download experience (although this add-on predates Chrome, by years). All downloads appear in a bar on the bottom of the window, instead of in a separate window.
DownloadHelper
This neat little add-on detects all the media being linked to by a website, including, and here's the awesome part, media linked to by flash player. This means you can now download YouTube videos and even music. Before Google decided to support HTML5 video, DownloadHelper could only download YouTube's .flv videos, which you would have to convert yourself. Luckily for us, Google has converted all videos on YouTube to mp4 (h.264/AAC).
DownThemAll!
DownThemAll! is a download accelerator. It uses torrent-like techniques to speed up downloads by breaking files into multiple chunks and downloading them simultaneously. From websites that can't serve content as fast as your internet connection, it can significantly improve download time. It also works well as a download manager and can automates rapid downloading of entire directories of files on the web, like image board threads.
F1
Fresh out of Mozilla Labs, F1 is a slick sharing add-on that allows you to share links to the currently loaded page very quickly, across a variety of social networks. It's incredibly quick, efficient, and useful.
Feedly
I'm a heavy Google Reader user, but the rigid interface of Google's site is a bit lacking. The people at Feedly have stepped in to correct this problem, by creating an add-on that integrates completely with Google Reader, allowng you to read RSS feeds in a much more attractive, functional, and efficient environment. It really improves the kinds of content you're shown, based on what you've read in the past and what your friends are reading. It's really a great add-on that every Google Reader user should try.
Firebug
Firebug is arguably the best tool for web development. It allows viewing, manipulating, and editing of HTML, CSS, and JavaScript, and it's really an invaluable tool to anyone in web design and development. If you use Chrome, it's basically a much more powerful version of Chrome's developer tools.
Flagfox
Flagfox is a small add-on that sits in your AwesomeBar, displaying the flag of the country in which the current page is based. It uses IP addresses to pinpoint thes location, and can also help pinpoint phishing scams.
Ghostery
In the interest of privacy, Ghostery is the ultimate anti-tracking add-on. It maintains an auto-updated list of URLs that contain tracking code, and blocks all content and cookies from those sources. Through this, it prevents sites from tracking your behavior.
HTTPS-Everywhere
Created by the EFF, this is a really useful tool that makes sure Firefox uses a secure connection when connecting to any website it knows supports HTTPS. If you don't know, HTTPS represents the HTTP protocol used for websites, but encrypted with SSL. The result is a connection to websites that can't be intercepted by a third party, protecting credit card numbers, login credentials, and any other sensitive data you might send to and from a website.
LastPass
LastPass is the best password manager available, in my opinion. It's an online password manager, which makes it accessible across devices, but that also means that your passwords are stored on LastPass's servers. Luckily, it's all encrypted, so that only you can access your passwords via your LastPass password. It's a much more secure, convenient, and useful option than the built-in optons inside Firefox and other browsers.
Lab Kit from Mozilla Labs
Lab Kit is an assortment of experimental add-ons by Mozilla that help increase Firefox's functionality, by adding things like F1, auto-complete in the AwesomeBar, and other in-development features.
Nightly Tester Tools
I'm a Firefox Nightly (formerly Minefield) user, and Nightly Tester Tools provides info like build numbers, profile management, and disabling Firefox's add-on compatibility checking.
Page Speed
Developed by Google, Page Speed is another web developer's add-on that helps you see how much time it takes every part of a website to load. Like Yahoo's Yslow, it helps devs etermine what might be slowing down their pages.
Readability
I've done a post on Readability before, but simply put, it's an awesome add-on for reading. It reformats webpages to be easier on the eyes, and offers a very customizable, comfortable, and convenient reading experience.
Restartless Restart
This restartless add-on (hence the name) adds a button in the Firefox menu to restart your browser at any time. It's small, but useful.
Screenshot Pimp
Despite my lack of fondness for the name, this add-on is very useful. It does just what it's name implies, enabling the easy and quick taking of screenshots of webpages.
Stratiform
This Windows-only add-on allows very flexible customization of the Firefox 4 user interface, from the olor of the Firefox button to the height of the tab bar.
Stylish
Though I don't really use it, Stylish is an interesting and powerful add-on that allows you to customize the ways websites look to your liking. It uses simple CSS files to do the customization, and if you know what you're doing, you can make some very cool redesigns of your favorite sites. It also offers a gallery of styles created by other users that you can enjoy their work, if you wish.
Tab Badge
As a compliment to the nice blue indicators on Firefox app tabs, Tab Badge adds a number signifying the number of notifications a webpage has for you, including unread emails, Facebook notifications, and the like.
Test Pilot
Simple add-on for participating in user studies to improve new versions of Firefox. It's the same add-on that was installed in the beta releases of Firefox 4.
Web Developer Toolbar
This toolbar adds a bunch of useful tools for web development.
Web of Trust
WOT is a very popular add-on that displays a ranking for every page, based on ratings by users on criteria such as trustworthiness, quality, and child-safety.
