A few hours after upgrading to Firefox 20, a bar was shown at the bottom of the window telling me that some data was being sent to Mozilla. the bar had a button labeled "Select which info" (or similar, I don't have a screenshot). Pushing the button did not more than opening the Options root page (the one with the row of icons at the top), and hided the bar.
Mozilla's help about that option (https://support.mozilla.org/en-US/kb/send-performance-data-improve-firefox) is outdated: it shows the old Options dialog, and refers to a checkbox that doesn't exist anymore in Firefox 20.

There is a new panel in Firefox 20 for those options - Firefox button > Options > Options (or Tools > Options) > Advanced > Data Choices

- Type about:telemetry in the Location/URL bar for a summary of the data

Thank you very much! The out of date help was confusing, but with your help I have found it.
i had the same question. i already had 'Enable Telemetry' and 'Enable Crash Reporter' disabled but i still got the popup. i'm not sure why firefox is saying it's automatically sending mozilla data when both options are disabled.
it used to say
will you help improve mozilla firefox by sending information about performance, hardware, usage and customizations to mozilla?
but that was changed to
firefox automatically sends some data to mozilla so that we can improve your experience.
this makes me think firefox is still sending data regardless. so are you saying that as long as both of those options are disabled firefox is not sending ANY info about me? if that's the case mozilla really needs to update the message. privacy policies are usually so vague and shadily written by lawyers that they are just about useless.
