Speed Dial - Probably inspired by Browser - Opera. I used Opera because of the Speed Dial feature attract me the most. Now Firefox can also have speed dial feature. Speed Dial will be automatically loaded in blank new windows. It can also load in blank new tabs.

Web Developer - 1 of my favorite firefox extension, probably I can’t live without :P. I think many peoples love this too (web developer, designer, pen tester). There are too many great features come together with this tools. For those people who I mentioned who work in this line, try it if you don’t.

DownThemAll - a powerful firefox download manager. Beside just a download manager like other do, DownThemAll can list you the current browser’s link to be downloaded. Like some other download manager, it support resume/pause download, split segment (contemporary) download,etc..

FireFTP - FTP that integrate into your Firefox. This client FTP can be handy if you have any better stand alone ftp client installed. FireFTP is easy to use (good for new FTP user) since it has no advance feature like other FTP client do. For developer/ designer, or some of my friends who connect to my files pool, they might love this.

GooglePreview - GooglePreview is a extension that give you thumbnail preview when you ‘googling’ over google search engine. Without entering to the actually website, it will give you a preview of how is the website look like..and of because the thumbnail is not real time update, so sometimes you might see difference from the thumbnail and the actual website.

IE Tab - This is really a cool extensions and probably this the reason why my Internet Explorer seldom to be used. IE Tab Embedding Internet Explorer in tabs of Mozilla Firefox, which mean without open with your Internet Explorer you can view the page as shown as in Internet Explorer under Mozilla Firefox. It has a switch tab for you to switch among Firefox and IE. This could be handy if you come across some website Firefox browser incompatible, just 1 click you will be jumped from Firefox to Internet Explorer.

ShowIP - ShowIP show the IP address of the current page in the status bar. This might be useful if you would like to check what the server IP addres (usually you don’t care :P), and sometimes you can easily spot a website with running on multiple IP. Beside show you IP, ShowIP also allow you to check the whois IP and hostname.

Live HTTP Headers - This is a tool to allow you to view HTTP headers of a page while browsing. From the headers, usually you can expect to see the web server banner, session ID. With this tools you can actually make it work like a web proxy. You can tamper/alter date and resend to server.

Server Spy - This tool will show you the web server banner (eg: IIS5 , Apache) on the task bar. A very simple tool but is a good piece of information to be display on the status bar.

SwitchProxy Tool - This is some sort like Proxy Manager Tool for you to easily manage and change your browser proxy setting. This tool could be handy if you often change your proxy setting (eg: proxy connection at office, direct connection at home), you can use put in some ‘free public’ proxy to keep you self anonymous while surfing to some website. Alternatively, you can try other firexfox extentiont called Torbutton.
