How to disable Mozilla yellow strip, reminding us constantly to "update a plugin", which we don't want to update. Details (RE: Flash) below: bobgorg@ymail

Hello, how to disable the long horizontal Mozilla yellow strip, popping up and reminding us constantly to "update a plugin", which we don't want to update. Disabling the ones below: 1/ plugins.update.notify User;true 2/ plugin.scan.plid.all;true 3/ dom.ipc.plugins.enabled;false either does not help or disables completely Flash! What else to do with this ultra annoying "Update plugins" reminder, as we want to keep the older version 10 of Flash? We just do not want Flash v. 11 - it takes huge amount of CPU, while Version 10 works fine for all 'you tube" and "etc"... videos. No need for V.11. (Let us worry about viruses and security) But here it comes the so annoying Mozilla reminder to upgrade to Flash Version 11 - the yellow strip also takes screen space under the address bar. Please help. Very annoying - almost ready to switch to other browsers if this issue is not resolve. Other than that, the Mozilla 14 is great. Congratulations to all designing it. Thanks in advance.
