Up to four or so days ago I was able to fire up my Linux and Firefox and had immediate access to both Gmail and Calendar. Now I am requested to sign in every time, are offered a Shareable Calendar (for which I have no use) and get a notification in my cell phone reporting a new login. Also, WhatsApp Web is requiring to link with my phone every time I want to use it in my laptop. I'm using Firefox 120.0 and this behavior appears to have started after the upgrade. I have also Vivaldi installed and its operation with the above pages is normal. This is most annoying. Have security rules been changed? Am I doing something wrong? Will appreciate any help you can provide.
