When attempting to view the attached video clips in certain bugs (see below for link to example) in Firefox, the user see a message displayed that reads "Video can not be played because the file is corrupt". The same attachments play in Safari without issue. This issue is not specific to these attachments or this bug, but rather is common occurrence when viewing video attachments in Bugzilla when using Firefox Browser. Issue noted today with .mp4 files, but I am not sure if issue is limited to this file type. link to example: https://bugzilla.mozilla.org/show_bug.cgi?id=1120869
