Webmail as default?

[jes]

I use Firefox 0.9.2 I am wondering if I can set my default mail client to use my webmail from my ISP?

I don't think so. Not just Firefox & your ISP's webmail, but any browser and any webmail. I don't know how to put it into words and explain why concisely, but I just don't think it's possible unless it's a specific browser built to do that with a specific webmail.

I recently read some speculation that Firefox will soon release a google branded version of its browser that will be tightly integrated with google & gmail.
