Gitako
File tree extension for GitHub on Chrome & Firefox & Edge
...It is more recommended for Edge users to install from the Chrome store. It may delay for weeks before updates got published to the Edge store because its review process is slow. Gitako doesn't share your private data at all. GitHub access tokens are required only when you access private repositories or exceed the GitHub API rate limit. Gitako stores access tokens in your chrome extension storage (not the LocalStorage) and use them only when authenticating with GitHub.
