I finally got around to do some research on the license provisions for Firefox & Thunderbird icons. Mozilla Foundation's art work is under copyright law, so a Creative Commons license does not apply. You may modify and distribute their icons within strict limits though. Most of all your work should be clearly distinguishable from their own stuff. That having said, I provide some links for further reading (mostly rather boring legalese). Probably the best way forward is to get in contact with the Mozilla Foundation and ask someone there. Maybe you could submit your work as the official icon for .xpi - files. It really looks nice, so why not ask.

I frankly do not know which license applies. When looking into info in Firefox and Thunderbird, there are many different licenses listed, but no Creative Commons. Probably the best way forward is to search the internet especially the website of the two projects. They surely have some information about which license applies to their artwork, although I guess it's something like the CC as GPL doesn't work well with artistic stuff, this is not source code. I'm sorry that I cannot help you further. In any case you should clearly attribute the icons to the original creators.
Please let me know if you find something - Aug 26 2011

I think you DO need to choose a license. Please take the time to think about it. I assume you do not want to use your icons for commercial purposes. You should probably choose a Creative Commons license. I would argue that the important point is that you do not want to see your work being used for purposes you don't agree with. Imagine a company taking them and then claiming you infringed on their copyright. This is a proposal, it's ultimately up to you what you want to do. You can choose a license that allows anyone to use the icons, modify them, and even to use them commercially. But the people should all attribute the work to you. - Aug 25 2011
