“Signal Desktop is now available in a new, standalone form, and the Chrome App has been deprecated.
The new desktop version of Signal runs independently of your browser. If you’re a Firefox or Safari user, you don’t need to install Chrome to send and receive Signal messages on your computer. If you’re a Chrome user, having your browser open will no longer be synonymous with having Signal Desktop open.”
Ein unabhängiger Messenger, nicht verbandelt mit irgendwelchen großen Angeboten. Hier noch weitere Informationen darüber.
