Cool Firefox add-ons

So, what cool Add Ons do you Firefoxers use ?

Mine are:

  • Adblock plus (blocks ads !)

  • Interclue (hover over a link to get a mini-preview popup)

  • PicLens (displays image searches as walls of large thumbnails - serious eye candy and very useful to boot)

So, what add-ons should I be downloading ?

I have

  • PDF Downloader: you can choose what you want to do when a pdf link is clicked, either download view in browser, view in adobe etc. very useful.
  • Downthemall: Useful tool for downloading, can pause/resume downloads if server allows it.
  • Stumbleupon: A fun toolbar that randomly puts you onto a website, very good time waster.

I run Firefox 3 and it does a pretty good job of blocking popups all on it’s little own.

Mmmm, PicLens is one of my favourites!

I also run the English (Australian) dictionary, so I don’t spell like a North American.

Firebug as well so I can figure out what’s happening with CSS stuff on web pages.

I appreciate that I’m a little on the nerdier side but I use each of these every day:

Drag and drop upload
You’ll wonder how you ever got on without it.

Firebug
Taking wysiwyg to another level - if you want to examine and manipulate code I know of no equal.

Greasemonkey
I’m even starting to write scripts for it. Changes pages based on YOUR rules. Eg: don’t auto-play videos on Myspace, show number of unread Gmail messages FIRST in title, have YouTube play the (beta) hi-qual version etc. See www.userscripts.org

Also PDFdownloader is a terrific little plugin.

TabsMixPlus
How can I forget - changed my life - essential for anyone that wants to run heaps of tabs. Adds labyrinthine menu options, undo closed tab menu, colour coding etc.

I too am on the nerdy side of firefox plugins (I work for an ISP) but I do like:

Flagfox (see what country a website is hosted in!)

Web Developer (I mainly use this for the Forms -> Show passwords feature. It is SO useful to be able to see hidden ***** passwords.)

Live HTTP headers (watches all of the in out HTTP transmissions. If you know what that is then you will find it useful)

I’ve had other ones in the past that I have really liked, like ones that colour your tabs which makes it easier to see them apart.
