Firefox is a huge part of what I do as a web designer (aka Pixel Pimp) and a Social Media Skank. Along the way I’ve gone through my fair share of crappy addons while keeping the ones I found most helpful. Here’s a list of the 18 addons I’ve kept around; hopefully you can find them useful as well.
Ay shawwwty, wha’yo flava iis?
This is a great addon that lets you get the colour reading of anywhere in the browser. It also has a colour picker with several palettes built-in.
An FTP program built into Firefox.
My favourite feature: Keep directories in sync while navigating.
I use it to measure the pixels of anything and everything inside the browser window.
Web Developer Toolbar
Several tools including working with CSS, forms, cookies, images, and more.
My favourite feature: Resize window (to 1024×768, 800×600, etc.)
Enables you to take full page screenshots of web pages with additional functionality like editing and annotating.
My favourite feature: Full page screenshots with a customizable delay for Flash movies.
Better Gmail 2
Includes a really nice skin for Gmail with additional options. A compilation of the best Gmail Greasemonkey scripts.
My favourite feature: Real file icons for attachments (instead of the paperclip)
Allows you to open your Del.icio.us bookmarks in your sidebar or in the browser window and tag/save websites.
Use your status bar to see the progress of your downloads instead of that annoying popup window.
Instead of having to browse for files when uploading or attaching to an email, you can simple drag the file to the input area of the form. The addon will automatically insert the path.
Foxmarks Bookmark Synchronizer
This extension saves your bookmarks to a server, where you can access it from any computer that has Foxmarks installed. Bookmarks are updated so you can take them with you anywhere you go.
My favourite Greasemonkey script: Pagerization.
Don’t you hate when links to PDF open in your browser? Or the take forever to open and freeze your system? PDF Download lets you choose how to open/PDFs and even gives you the option of converting it to HTML.
The best addon for sharing content on the web, period.
Great addon for random stumbling, sending sites to your friends and stumbling via interests or through various websites.
Great addon for twittering on the down-low. Just type your tweet in the location bar and send away.
My favourite feature: TwitterBar lets me know how many available characters I have left in my tweet.
What addons would you recommend?
