The first concerns Thunderbird and sending emails, the second concerns Firefox, Google Street View and screen shots.
In the past, when I sent an email via TB, it put a copy directly into my 'sent' file. Fine, I'm happy with that and used to it. But recently, as well as putting a copy in my 'sent' file, it's also been sending me a copy, so that a couple of seconds after sending, the computer 'pings' and a copy appear in my inbox. I can stop this simply by deleting the cc message on the address list before I send it, but it never used to appear there, and I have to remember to delete it before I send, which is mildly annoying. How do I stop it automatically sending me copies? I can't see anything relevant under Tools>Options etc.
Again in the recent past, when using Street View in FF, right-clicking the mouse brought up a little menu containing the option to take a screen shot. I have used this quite recently when using Street View, but it doesn't seem to be available any more, although it is still available for other FF screens. Is this due to a change in FF, or can Google Street View now disable the screen shot facility remotely, or what, and is there any way I can get it back?
