    Moderators, please move this topic to if the crashing is not specific to pre-release Sierra.

    I tried twice to upload a file, both attempts led to a crash of Adobe Flash Player – reported within Firefox, but clicking for more details failed to present details.

    The crashes occurred before a file selection dialogue could appear.

    Not reproducible with Safari.

    The player is up-to-date.

    Uncheck "Use the Flash-based uploader to upload attachments" in Preferences.

    Thanks, I'll do that.

    If someone else can make the problem reproducible, and if it's specific to Sierra, that person might like to feed the bug to Apple.
