Hmm as I remember, Netscape has the tab browsing feature for quite along time ago. IMO the best thing about firefox is its ability to "fake" IE or Netscape when needed (plugin required).
EditPlus or Notepad I don't like Front Page, it creates too much redundant code.When I loaded Dreamweaver, it pop up with some thing like 10 windows all over the screen. That freaks me out andyy15 : If you're using notepad, save the file you're editing. Open it in your browser. If you want to see the changes just swap to the browser and refresh.
