This is way cool: try out the developer preview release of Firefox’s latest browser, version 3, beta 4 via the good folks at PortableApps.
What’s even cooler is that you can download this latest version without messing up your current string of add-ons in your stable Firefox version. From PortableApps:
Install Note: The 3 Beta 4 release will install alongside a Mozilla Firefox, Portable Edition 2.0 installation by default and show up in your PortableApps.com Menu with a “Test” suffix. The installer supports upgrading existing 2.0 installations by manually changing the install location as well.
Well, at least this fixes one of the issues with trying out new things before you install/replace an existing tool in your computer–put it in your thumb drive!
