AllPeers - the P2P tool built into FireFox

AllPeers is officially available starting from today. AllPeers is a P2P plugin for Firefox, with a total size of up to 3900 KB. Through AllPeers, you can share files with your friends and send photos, videos, music, or other files back and forth. The operation method is relatively convenient; you can perform file sharing and similar actions simply by dragging and dropping. Additionally, AllPeers enforces file-sharing permissions very strictly. If there's no one in your friends list, you will basically not be able to download anything, because it does not offer functions like file search. In other words, you cannot download files from people you don't know. Therefore, AllPeers is only suitable for file transfer and sharing among friends. An AllPeers icon is also placed in the system tray, and when you close Firefox, AllPeers continues to run, so there’s no need to worry about downloads being interrupted.

The official AllPeers website provides a video tutorial that you can refer to for understanding how to use it. You can also directly download this plugin through this link.
