App Notes

The beta release will install alongside a standard Firefox Portable install in a FirefoxPortableTest directory. Note that will release one version for each major version (example: 61b1 but not 61b2). 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."
