John at PortableApps.com has released an updated version of Portable Firefox. However, it’s now called Mozilla Firefox – Portable Edition, or Firefox Portable for short, due to trademark reasons.
This new release adds in a ton of new features, including: the ability to run from a CD, partial upgrade support, in-place upgrades, lots of handy bug fixes, support for running within Wine on *nix and more. And this release is also paired with releases of Firefox Portable 1.0.8 and Firefox Portable 2.0 Beta 1 using the same updated launcher, for all the web developers and testers out there.
Take it with you anywhere you go on your USB stick. I love it!
