Exhibit A:

105.224.aa.bb - - [18/Feb/2013:00:21:02 -0800] {yata, yata} "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:18.0) Gecko/20100101 Firefox/18.0"

Exhibit B (same person, which is why I noticed):

105.224.cc.dd - - [21/Feb/2013:19:41:48 -0800] {yata, yata} "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:19.0) Gecko/20100101 Firefox/19.0"

Exhibit C (I suspect this is a fake, though apparently human; it's the earliest I find):

72.186.12.51 - - [19/Nov/2012:20:05:41 -0800] {yata yata} "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:19.0) Gecko/19.0 Firefox/19.0"

Exhibit D (the second-oldest, still with grounds for suspicion):

174.53.82.230 - - [13/Jan/2013:23:32:47 -0800] {yata yata} "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:19.0) Gecko/20100101 Firefox/19.0"

Guess they got tired of updating the UA when the decade rolled over, because it's never advanced past 20100101.

Thanks to Firefox's long-standing belief that "Check for updates" = "Download and install updates" I had time to dig around in the far reaches of the prefs. Now, I know for a fact that I've owned this computer since June of 2010, but this is as far back as it goes.

Dear Firefox.

Dear, dear Firefox...

Is there anything we can do to help?
