I’ve been a happy Firefox user for quite some time. I even run on nightly builds on a daily basis (the new auto-update feature of upcoming 1.5 release makes it really easy). I’ve tried quite a few firefox extensions so far, below is a list of some that I’ve found to be invaluable.
If you’re using a nightly build, or a beta and some of your extensions are disabled, use the Nightly Tester Tools extension to enable them again.
Web Development
- Web Developer
An excellent extension, worth getting firefox just for this. Too many features to mention here. Invaluable. - Inspect Element
Adds an option in the context menu which when clicked will take you to the respective element in the DOM Inspector (built-into firefox). - Console²
Console² is an enhancement over the default Firefox Javascript Console that let’s you display errors filtered by type (Errors, Warnings, Messages), language (JavaScript, CSS, XML) and context (Chrome, Content). Furthermore it provides a simple search box (as seen in the History and Bookmarks sidebars) and some accessibility improvements. - IE View
Adds an option in the context menu to quickly load current page in IE, for comparisons.
Usability enhancements
- Greasemonkey
Allows the customisation of pages through Javascript. You can find a wealth of ready-made scripts here. Unique. - Adblock Plus
Get rid of ads, once and for all. - BugMeNot
Another form to fill out, another service that needs registration? Right-click on any form field, select bug-me-not and this extension will load user-supplied information from a central site to automatically fill it out and submit!
Brilliant! - PDF Download
Gives you an option to either download a PDF, view it in another tab using Acrobat Reader, or as HTML! - Tweak Network
This extension will allow you to tweak network settings to improve performance. - Feedview
Displays RSS feeds as a regular web-page. - FlashGot
Integrates 3rd party download managers (such as get-right) nicely into firefox. - Google Toolbar for Firefox
All google goodness in a toolbar which is customisable. - Stop-or-Reload Button
Replaces the Stop and Reload buttons with one that changes state appropriately. Nice if you want to save some space. - Tabbrowser Preferences
Provides several options to customise your tab-browsing experience.
