Catalyst 10.12 is the version I have currently.

I can confirm, Catalyst 10.12 with ATI Radeon 5800 series, other information is there but no date.

Same here with Catalyst 10.12 on a Radeon HD 5770.

It was also missing with whatever I had installed prior to updating to 10.12 tonight. (I think I was on 10.10, but don't remember for sure.)

Looks like I found out a reason of this issue.
Apparently Firefox looks in registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\0000 for "DriverDate" key. It looks like:
"DriverDate"="11-25-2010"

The problem is length of this key. If I change this key to something like:

"DriverDate"="9-25-2010" or
"DriverDate"="11-2-2010" or
"DriverDate"="11-25-201"

driver date in about:support is shown.
Looks like Firefox can not show driver date that consists from 8 digits.

That key's for me is "5-14-2009", and I'm not seeing Driver date in about support, so this sounds right. 

That exact key's for an old, uninstalled Nvidia video card for me, though. My current ATI card's DriverDate key's value is "11-25-2010": 
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\0000

So, this?

Attachment: fix calls to RegQueryValueExW

RegQueryValueExW's last parameter is in-out and needs to be set to the appropriate value before every call. That might or might not be the reason for this bug.

Someone landed this already.
