App Notes

The developer release will install alongside a standard Firefox Portable install in a FirefoxPortableDeveloper directory. Note that PortableApps.com will release one version for each major version (example: 99b1 but not 99b2). For updates within each major release, use the internal updater. From Mozilla: "This is pre-release software: you may encounter compatibility problems with some websites and add-ons."
