The FireFox AddOn I am using:
1.
|  | FireBug, as a web developer I must recommend this one. it's simple to use and powerful. you can trace your javascript, check your DOM structure, and ...... a bunch of powerful stuff. | 
|  | Web Developer ok, you already knew that I am a web developer. so you should not be surprised that I am using this addOn. | 
|  | del.icio.us bookmarks If you do not know what del.icio.us is, you should go check it now. right now. I mean it. stop reading.... | 
|  | FireFtp It's handy to have a ftp client built in your browser. | 
|  | FlashGot I switched to mac last year, so this one does not help me any more. I started to use Downthem! All instead. But If you use windows, and you are a flashget user. you should check it out. | 
|  | Downthem! All easy to use, if you often find yourself repeatly using right click and save as... in one web page. trust me, you definitely need this one. |
