title: Is there any way (perhaps some kind of hack) to ignore specific errors/warnings in Firebug?
body: <p>As a web developer I use Firebug constantly, and I've had just about enough of these persistent errors/warnings that always show up no matter what.  One of them is the "The Components object is deprecated" error (which should be a warning) and the other is "Exposing chrome JS objects to content without <strong>exposedProps_</strong> is insecure and deprecated".</p>
  
  <p>I've taken a screen shot of the three items I get all the time no matter:  <a href="http://snaps.vertigofx.com/009/snap1330_2013-03-27_06.54.41.png" rel="nofollow">http://snaps.vertigofx.com/009/snap1330_2013-03-27_06.54.41.png</a></p>
  
  <p>Sometimes I get other errors/warnings, too, and like the ones I already mentioned they are not related to anything I am working on, so I just have to try to ignore them.  However no matter how "used to them" I may think I be, when I see that red text I automatically think I've broken something and it just bugs me.</p>
  
  <p>I just recently upgraded Firefox to 19.0.2.  Before that the errors/warnings were even worse, but they're still not gone.  I've found one forum thread on the internet regarding the "Components object" one and the original poster said he got it to go away but wasn't specific enough on what that was.</p>
  
  <p>Anyway, if anybody knows what I can do to rid myself of these, I would really appreciate it.</p>
