A lot of excellent suggestions and explanations. Most appreciative, thank you. Though my money is on Malware and/or the Feds. There’s just too much going on now and the fear level is high amongst the illegally elected pols. And this only happens on FR, nowhere else, so it isn’t likely to be my equipment or programming (Windows 10) or even the browser itself, unless it has been enlisted in their cause.
Restart your browser.
Restart your Win10.
Sometimes an external program will ‘capture’ the input. A reboot usually clears that up.
If you find out what your browser/FR posting glitch is — hope you do — pls CC me.
