After updating to v120 my Firefox started behaving strangely. With v119 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. It would appear that the problem lies in syncing as WhatsApp Web is also requesting scanning its QR code every time too. This is most annoying. No settings were changed after the update. As a temporary solution I grabbed a v119 tar.gz from my wife's laptop and installed it in mine. Now all is behaving normally as before. Am I doing something wrong? Will appreciate any help you can provide.
