Bug description

With Firefox: When playing a video file in Files, it appears the file is downloaded/buffered again on every playback, i.e. the video plays, finishes, then playhead goes back to 0:00. Hit play again, and the files is downloaded anew.

Steps to reproduce

Files > open video file
play the video to the end
hit play again.
wait for file to buffer again.

Expected behavior

Expecting the file to be stored locally for instant playback instead of downloading on every "play"

See repeated 9.71MB download: (Note, ignore the two other large video downloads, those related to nextcloud/viewer#2586 )

Are you sure you don't have caching disabled somehow? Seeing the Dev tools opened for example :)

gerbrent commented 1 month ago

Great question! The "Disable Cache" option in the dev tools is disabled. Caching in the browser seems... normal and not specifically disabled.

Tested in a Chrome-based browser (Chromium) and behaves as expected 👍🏻

Tested on a different OS, on a fresh Firefox profile and the behaviour persists, so clear to say this is a Firefox-related issue.
