Hello,
Lately scammers have been posting   (mainly in threads where no reply has been posted yet),   claiming to be Mozilla experts and asking users to either call a so-called toll-free phone number or giving them a link to a site, where they are promised to get expert help.
These posts of course are scams.
Hopefully informing you about this will scare them off and you won't see such scam post.

Thanks McCoy but didn't answer my query.

Of course not;   I'm sure that some other contributor will answer your questions asap.

Right now I'm too busy warning all users about these scammers.
