Firefox as development platform?

FireFox has been my browser of choice for quite some time. I am the kind of guy who likes customization. There is a certain ways my computer has to be set up, its just the kind of person I am. Perhaps for me the most important feature of FireFox would be plug-ins. This is the best tool for customization of your browser. Now, I have been impressed with newest Internet Explorer, add-ons are step in the right direction, but at this point there are no add-ons to help with coding, but when it comes to FireFox, well, let me just list some:
Most obvious - Web Developer – lets just say that this is a must have if you are coding for web. List of features is just too long and I am just to lazy to list everything, lets just say without it any kind of coding for web would just take too long.
Firebug - simply put one of the best tools for debugging your web site. Add YSlow and get in depth analysis of what is going on with your project.
Pencil – free and quite powerful tool for UI prototyping and diagrams, try it out. It won’t replace industry standard software, I for one prefer Visio or coffee shop napkins and black pen, depends on where the idea strikes me, but if you need to do something quick, Pencil would do just fine.
FireFTP I can’t really count number of times I needed to ftp something quickly. FireFTP serves just that purpose. I can’t really recommend it for transferring bunch of files, keeps on timing out, but then again, I have not really played with all settings to affect that.
Codetch - an IDE like plugin which lets you work with your files in a manner similar to Dreamweaver. Once again, for a full blown project I would use a stand alone IDE, most likely Visual Studio or Komodo Edit, but for a quick change Codetch does the job.
There are more, much more. These are the things that I use quite often. Now, with all that great functionality, would I consider FireFox as a development platform? The answer is no. There are tools that are designed specifically for development purposes, while FireFox is a browser. It might be handy to keep a jump drive with overloaded FireFox installed handy for some quick coding while your machine is unavailable, but for full blow development project, there are tools that can do the job much better.
