I have Mozilla firefox 38.0.1, so can I uninstall 30.0?

The only problem is that if ver 30.0 is not needed to use ver 38.0.1, I'd like to free up the 69 megs it takes up on the hard drive.

Could you check and see whether there are multiple Mozilla Firefox folders here:

C:\Program Files (x86)\

If you only find the one, then I suspect that Firefox 30 actually was replaced by a newer version, but something glitched and Firefox 30 was left in the uninstall section of the Windows registry.
