# Firefox Sync Server for YunoHost [](https://dash.yunohost.org/appci/app/ffsync)   [](https://install-app.yunohost.org/?app=ffsync) *[Read this README is other languages.](./ALL_README.md)* > *This package allows you to install Firefox Sync Server quickly and simply on a YunoHost server.* > *If you don't have YunoHost, please consult [the guide](https://yunohost.org/install) to learn how to install it.* ## Overview The Sync Server provides a replacement for Firefox’s default server (hosted at Mozilla). By default, a server set up will defer authentication to the Mozilla-hosted accounts server at [https://accounts.firefox.com](https://accounts.firefox.com). So you will still have to authenticate at Mozilla, but _the storage of your information will be done on your host_. ⚠️ This app is **deprecated and replaced** by [syncstorage-rs](https://apps.yunohost.org/app/syncserver-rs). **Shipped version:** 1.9.1~ynh5 ## Disclaimers / important information ## Configuration Once installed, reaching `http://domain.tld/path` should show a page explaining how to configure it. ### Solving problems with Android The sure-fire way to know what Sync on Android is really doing is to observe the Android device log using adb logcat. You’ll want to bump your log-level: ``` adb shell setprop log.tag.FxAccounts VERBOSE ``` Then, you can observe the log using: ``` adb logcat | grep FxAccounts ``` It’s best to observe the log while you force a sync from the Android Settings App. You should see output like: ``` D FxAccounts(...) fennec :: BaseResource :: HTTP GET https://token.stage.mozaws.net/1.0/sync/1.5 ... D FxAccounts(...) fennec :: BaseResource :: HTTP GET https://sync-4-us-east-1.stage.mozaws.net/ ``` ## :red_circle: Antifeatures - **Upstream not maintained**: This software is not maintained anymore.
