Mozilla has made privacy Firefox's calling card, while lambasting companies it believes don't meet the bar on security. Its latest update to its web browser, an end-to-end encrypted file transfer service, fits the mold. Firefox Send was introduced in 2017 as part of the now-defunct Firefox Test Pilot, which allowed early adopters to try out experimental features, and is now being graduated. Those with Firefox accounts can now share files up to 2.5GB in size between browsers, while everyone else is limited to 1GB. It's also getting its very own Send Android app in beta.
