Re: Logitech unifying software not supported
It's not up to the browser to support particular hardware but the hardware maker to support the most popular browsers. Add to that the fact that the system I am responding from is running Logitech Unifying software to access the M510 mouse and Illuminated Keyboard so apparently it can work with Firefox in some configurations.
Have you confirmed that you are running the latest version of Firefox and the latest version of the Logitech software? Does the same issue exist if you launch the application in Mozilla Troubleshooting Mode? http://kb.mozillazine.org/Safe_mode

Re: Logitech unifying software not supported
(Rather late to this post) I'm also running Logitech Unifying software with a M510 mouse with no real issues with Firefox. Been using it for many years. Any messages about incompatibility would likely be coming from your OS, not Firefox. If I recall correctly, Logitech said the software/mouse is incompatible with my OS Win 11. It still works.

Re: Logitech unifying software not supported
I believe the OP is speaking about the website itself, https://logiwebconnect.com/, not anything to do with KB hardware or KB related software on ones computer.
The site does state, "Supported browsers: Chrome, Edge & Opera latest versions." - so in other words, Chrome.
That said call Logitech & tell them that since they do not support your browser, you will not support their hardware, & return your KB & buy ... some other brand, instead.
They won't care, but it might make you feel better
