Today Firefox on my laptop will not open. There is a message (?from Google?) saying it is because cookies are switched off. I have not knowingly made any changes to cookie settings or installed any new features. A new Windows update installed recently (I am on Windows 11) and also a new version of Edge (although I never use Edge myself). The Google guidanc eon how to fix the situation only deals with Chrome. So how, please, can I get Firefox working again?
