I am looking for a way to maintain LAMP-based websites entirely from a browser window.
Currently I\'m using FlashFXP and NoteTab Pro for FTP and cod
As said in tj111 answer (Web-based FTP client & code editor) you could install fireFTP and FireFOx portable to be able to run firefox from a USB-stick.
Then you could on the same USB-stick install notepad++. It's a great open-source editor with syntax highlighting and parameter hinting and a lot more. (http://notepad-plus.sourceforge.net/nl/site.htm)
Then you could run both fireFTP and notepad++ from that USB-stick. You can configure fireFTP to automaticly open files with notepad++. When you'll save the file in notepad++ fireFTP will automaticly update it on your FTP server.
