Incorrect/Changing browser icons?

[RedStripe 14]

1) The Media Browser bookmark icon is sporadically changing. I've tried to determine what action may be causing it to change but I cannot, I just notice that from time to time it does. Could Media Browser be causing this? (P.S. I am using Firefox 31.0)

Screenshots:

2) Is the MediaBrowser tab icon the correct one? It does not appear to fit in the allotted space.

 

Thanks

The ones from the first image is the "new" one, as it appeared for me a couple of weeks ago, the image from the 2nd image top right corner is the "old" one, maybe it has to do with cache or something ?
