Since the last update of FFx its behaviour is impossible. I'm using it on two win 10 machines, and on both of them Ffx freezes, locks me out and doesn't react to any kind of clicking. This happens especially if I'm writing mails (gmail), but also when I'm filling out forms, like the log-in form for CC. Has anyone else experienced this?

me too

Have you been able to sort it, or do we have to wait for Mozilla to send out a new update?

The 64-bit edition of Firefox (called Waterfox) doesn't seem afflicted by these problems in the latest updates of Windows 10.
