Summary: Linux appears to spawn a completely separate browser process whereas MacOS either forks or uses a thread. Either way, Linux no longer has access to the parent process's environment variables we use to look up plugins. Using the remote module fixes that. In the medium term, we should convert the `plugin` module to not rely on import effects and instead use the IPC mechanism, making the plugin resolution asynchronous: https://electronjs.org/docs/api/web-contents#contentssendchannel-arg1-arg2- That would also allow us to do the plugin resolution while starting up the browser window, lowering the startup time.

Flipper 
Flipper, formerly Sonar, is currently in the process of being renamed. This may cause some inconsistencies until everything is in place. We apologize for any inconvience caused.
Flipper is a platform for debugging mobile apps on iOS and Android. Visualize, inspect, and control your apps from a simple desktop interface. Use Flipper as is or extend it using the plugin API.

Mobile development
Flipper aims to be your number one companion for mobile app development on iOS and Android. Therefore, we provide a bunch of useful tools including a log viewer, interactive layout inspector, and network inspector.
Extending Flipper
Flipper is built as a platform. In addition to using the tools already included, you can create your own plugins to visualize and debug data from your mobile apps. Flipper takes care of sending data back and forth, calling functions, and listening for events on the mobile app.
Contributing to Flipper
Both Flipper's desktop app and native mobile SDKs are open-source and MIT licensed. This enables you to see and understand how we are building plugins, and of course join the community and help improve Flipper. We are excited to see what you will build on this platform.
