symlinks missing after complete MAR file update
While testing using MAR files from our own nightly build, brade and I discovered that the meek symlinks (present on Mac OS) are removed after a complete MAR update is applied to TB 4.0-alpha-3. The problem is in the MAR file generation – specifically, we neglected to include the addsymlink directives in the updatev2.manifest file (we only put them in the new updatev3.manifest file that is used by ESR31 and newer browsers).
