Clipsync is an app for syncing your clipboard across devices. Firefox does not allow reading from the clipboard by default, and clipboard access cannot be enabled for just one website. Because of this, when you trigger a paste event with a keyboard shortcut in Firefox, Clipsync does not have the capability to read the clipboard.
This extension has specific permissions to read the Clipboard and can send the result back to Clipsync for pasting into the cloud.
