Thank you John for all your hard work on creating Portable Apps. I use them throughout the week and look forward to the new Thunderbird 1.5 once it's adjusted for portability.
I've thought about asking for information on your Portable builds so I can make a PortableFirefox and PortableThunderbird for Mac OS X. I also use a Mac at home, and most of my family uses them.
But what I've really wanted a Cross Platform PortableFirefox & Thunderbird since I use Macs, Windows and Linux platforms - at home, work, family & friends.
Luckily, I just stumbled across this and thought it should be listed - PortableFirefox for Windows & Mac OS X. Seems them extended your work.
Have you considered partnering your work with others to create Cross Platform PortableFirefox & Thunderbird? (BTW, I understand that Open Office and others would be a bit much since most people want email & web anyway.)
Thanks Mark S.
