Who among us has not made the mistake of sending a 'broadcast' email to a large number of recipients without using BCC; thereby revealing everyone's email addresses to all?
Use Bcc Instead is a Firefox extension that attempts to prevent this from occurring. It does so by checking each email, upon sending, to see if it is being sent to either non-BCC'ed mailing lists or to more than a user-configured number of recipients who have NOT been BCC'ed. Should this occur, the user is either warned or the email send is prohibited.
PLATFORMS:
I have personally tested this version of the add-on only under Windows XP Pro. I have every reason to expect that this add-on will work on other platforms as well - please let me know what you find.
DETAILS:
After installation, this add-on will inspect the recipient list for each email sent. It will count the number of recipients to see how many are NOT being BCC'ed. If that count exceeds a value set by the user in this add-on's options panel or if any recipient is a non-BCC'ed mailing list, this add-on will take action to help prevent the unintended revelation of recipient email addresses.
The action that this add-on takes depends on how the user has configured a second setting in the add-on's options panel. By default, a warning message is displayed giving the user a chance to reconsider the sending of the email. This option can be changed to simply prohibit the sending of the email.
OPTIONS:
This add-on offers two user-configured options which control its behavior. These can most easily be manipulated via the built-in add-on options dialog. To access this dialog, go to the Tools menu and select 'Add-ons'. You will see a list of installed add-ons and 'Use Bcc Instead' should be in the list. If not, the installation did not succeed. If so, just press the Options button. These options do not require a restart of Thunderbird to take effect.
