This article explains how to use the To, CC and BCC fields when addressing an email.
To: The primary recipient(s) of this email.
CC: (Carbon Copy) The secondary recipient(s) of this email. People in this section will see the email addresses of those in the To: and CC: field.
BCC: (Blind Carbon Copy) Addresses in this field will have mail sent to them but they won't know who else was in the BCC field. That means that those in the BCC field will receive the email but those in the To and CC fields won't know who was in the BCC field.
If there is an entry in the BCC field and not in the To field, the email will be sent to all the BCC recipients and will be displayed as being sent to "undisclosed recipients" or similar wording by the receiving email program.
Gmail will remove the names in the BCC list from your sent folder. That means you will have no record of to whom an email was BCCed. If you need a record of whom you BCCed in an email, you will have to manually record this yourself before sending the email. This only applies to Gmail accounts.
Tip: Email providers limit the number of people that you can send an email to. Please check your email provider's website for the exact limit. If you need to email lots of people, it's better to use a mailing list or a bulk email service.

It's helpful for Mozilla's engineers to be able to measure how Firefox for Android behaves in the real world. The Telemetry feature provides this capability by sending them performance and usage information. As you use Firefox, Telemetry measures and collects non-personal information, such as memory consumption, responsiveness timing and feature usage. It then sends this information to Mozilla on a daily basis and we use it to make Firefox better for you.
Firefox also has a Crash Reporter feature that warns you when Firefox closes unexpectedly, and allows you to send this information so the engineers can make Firefox more stable and secure.
You can turn this feature on or off at any time in your Settings:
