    Default Firefox behaving badly.

    Has anyone else had issues with the latest versions of FF behaving badly with zimbra?

    I am getting more and more uses complaining of not being able to open their attachments with FF unless they fwd them to them selves but on other browsers or even other machines with FF it works fine.

    Also now some are getting errors when trying to attach pdf's etc in FF... but again use another browser it doesn't happen.

    I am very seriously considering dumping FF and going back to Ie or Chrome as the complaints just aren't stopping.. this has only happened since FF3, and or 5.0.9 of ZCO.

    Uninstalling FF and reinstalling it doesn't fix it but a total reinstall of the PC does... odd.

    The problem is probably in the users' mimeTypes.rdf file. If so, consider voting for
    http://bugzilla.zimbra.com/show_bug.cgi?id=32536

    How the problem usually starts: your users download a file from a web server with a bogus mime.types file. Firefox stores the mime type in the user's profile. User goes to upload a file with the same extension to zimbra webmail. Firefox tags it with the (bad) saved mime type, which the Zimbra server doesn't validate.

    I think your right, but now it's getting out of hand.. as of this morning I have a list of 22 machines this is effecting.

    removing the mimetypes.rdf has not resolved the issue.. before you could just fwd these problematic attachments to yourself and they would open, now you can't and have to open them on a machine that this doesn't effect.

    So far the only solution we've found is to do a complete reinstall of the PC.. there must be a key in the registry that is getting hosed as well.

    Post the source (at least the unaltered MIME structure) of a message that doesn't work.

    Firefox doesn't store anything MIME-related in the registry.
