As if it wasn’t bad enough that they want me to use a random internet service to add a keyboard to a usb wifi receiver, they have the balls to put this for Firefox users. I clicked out of pure curiosity, as I’m not even remotely interested in involving a corporate internet service in getting my keyboard connected to my computer. This is the message you get now on Logi Options software if you have a Unifying Receiver:

EDIT: some people on the thread have brought up that the error message being displayed for Firefox users is due to the WebUSB API not being implemented by Firefox due to security concerns. This still does not justify having to use a web app to plug peripherals to a PC.
Not the Logitech I became a fan of, glad they updated the name to Logi reflecting they’re half the company they used to be.
I miss the old Logitech software and Logitech Gaming Software, from like 10 years ago.
Now I can’t even launch the driver software to adjust my webcam or mouse behavior from my work computer because of legitimate Internet security settings preventing random background apps from exfilteating data, which is exactly what it’s trying to do.
Customer support of course blames the user for their app that will never finish loading until it talks to the mother ship.
In fairness to me this kind of thing is nothing new on Logitech’s part. Back in the XP/Vista days, Logitech refused to follow established usb standards for things like webcam’s and the like. So we depended on Logitech providing drivers, which they didn’t bother doing for a lot of their hardware beyond XP. So all of a sudden a 1 year old bit of hardware wouldn’t work on Vista because reasons.
Logitech and Creative Labs were the absolute worst for forcing proprietary tech and then refusing to support it properly.
