Firefox extensions everyone should have...

Extensions are by far one of the greatest things about the web browser Firefox, so I'm going to follow in the path of my friend Justin by sharing some of what I think to be the coolest extensions which everyone ought to have on their Firefox browser. Feel free to suggest any of your own personal favorites as well.

1-Click Answers

"1-Click Answers TM will save you even more time with AnswersTips that instantly deliver the information you are looking for. Just point at any word, hold the Alt key and click. Upon letting go, an AnswerTip in the form of a pop-up "information bubble" appears on the screen explaining the term."

VideoDownloader

"Download videos from Youtube, Google, Metacafe, iFilm, Dailymotion... and other 60+ video sites! And all embedded objects on a webpage (movies, mp3s, flash, quicktime, etc)! Directly!

VideoDownloader add a small icon on the status bar at the bottom of your firefox window, and a toolbar button. Just click that and download the video you are watching!"

*And if you don't want the extension, it's worth noting that you can still do it manually, by copying and pasting links into the top line of this website: http://javimoya.com/blog/youtube_en.php

*And you'll need an .flv player, so I recommend this free one:

Adblock

"Once installed, it's a snap to filter elements at their source-address. Just right-click: Adblock: done. Filters use either the wildcard character (*) or full Regular Expression syntax. Hit the status-element and see what has or hasn't been blocked."

In other words, you shouldn't have to deal with any picture ads while web browsing any more!

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. Filterset.G is an excellent set of filters maintained by G for Adblock that blocks most ads on the internet. In addition, this extension allows you to define your own set of filters that you can add along with Filterset.G during an update."

That is to say, this is the easiest way to keep your Adblock extension up-to-date.

Tab Mix Plus

"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. It also includes a full-featured session manager with crash recovery that can save and restore combinations of opened tabs and windows."

FoxyTunes

"Do you listen to Music while surfing the Web? Now you can control your favorite media player without ever leaving the browser and more...

Supports WinAmp, iTunes, Yahoo Music Engine, Pandora, foobar2000, Windows Media Player, Xbox Media Center, Musicmatch, Quintessential, J. River, jetAudio, XMPlay, MediaMonkey, Media Player Classic, Sonique, wxMusik, Real Player, XMMS, Noatun, Juk, Amarok, Music Player Daemon, Rhythmbox and many other players.

Just click on the orange note and select your player."

ForecastFox Enhanced

"Enhanced version of the popular Forecastfox extension (forecastfox.mozdev.org) by Jon Stritar and Richard Klien. This adds 12 improved radar images and the ability to supply a URL for your own radar image. It also allows for pausing, restarting and setting the frequency of automatic updates."

This version is far better than regular forecast fox. The only downside (as with the original) is the reliance upon Accuweather, which seems to be slightly less accurate than weather.com, from my own experience.
