* __Technical data__: Firefox sends data about your Firefox version and language; device operating system and hardware configuration; memory, basic information about crashes and errors; outcome of automated processes like updates, safebrowsing, and activation to us.  When Firefox sends data to us, your IP address is temporarily collected as part of our server logs.

We may access your uploaded screenshots when reasonably necessary for the operation of the service.  You can delete your uploaded screenshots at any time.
