I use WhatsApp in a Firefox web window so that I can copy, paste, and type using my keyboard. Suddenly beginning last week Firefox will not let me paste in the WhatsApp web window. dom.event.clipboardevents.enabled is TRUE I still have the same issue in safe mode Ctrl-V, Shift insert, Right click & Paste, Right click & paste without formatting are all disabled. It is only Firefox that has a problem (I can use WhatsApp in Chrome without issue). So far, it is only in WhatsApp (where paste is most important to me) that I have a problem. I have Firefox 116.0.3 64 bit, the latest version, running in Windows 11, which is up to date. Any ideas?
