It does not use too-much unnecessary Permissions & Accesses  and does not collect private data from phone. THANKS. It's browser-core engine needs to be updated. And it would be better  if it does not use ""Precise (GPS & Network) Location"" Permission & data. A separate plugin-app Tinfoil-Facebook-Location can access location  and users who need that location feature/functionality can separately load+use that plugin-app.
