Quote:Firefox Screenshots has been a smash hit for Mozilla; initially launched as the Page Shot experiment as part of the -- now retired -- Firefox Test Pilot program, it was later integrated natively in the Firefox browser.

Firefox supported screenshot functionality previously; Mozilla added screenshot capabilities to the -- now also removed -- Developer Toolbar.

Screenshots provides Firefox users with a native option to capture webpages. The initial implementation supported uploading screenshots to a Mozilla-operated server for online access and sharing, and local saves.

Mozilla implemented the functionality in a way that was confusing to users as "save" did not save the screenshot to the local system but online on Mozilla's server. Mozilla planned to address this by renaming save to upload.

The change won't be necessary anymore going forward, however, as Mozilla revealed that it plans to shut down the upload capabilities of Firefox's screenshot tool.

In other words: starting with Firefox 67, screenshots can only be saved to the local system.
