(Firefox :: Untriaged, defect)

Attachment: useragent-issue.png

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:25.0) Gecko/20100101 Firefox/25.0 (Beta/Release)
Build ID: 20131028113246

Steps to reproduce:

i use a site-specific useragent override to trick outlook.com into giving me the "light interface". as of firefox 25 (i patched yesterday), this stopped working. 
To accomplish this, I had set:
general.useragent.site_specific_overrides=true
general.useragent.override.outlook.com=light owa plz
I went into about.config and set 
general.useragent.enable_overrides=true
and it still doesn't work.
i'm on linux if that matters.


Actual results:

using live http headers addon, i can see that my browser is sending to outlook.com, e.g.:
GET /owa/14.16.359.5/themes/base/csssprites2.png HTTP/1.1
Host: r3.res.outlook.com
User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:25.0) Gecko/20100101 Firefox/25.0




Expected results:

i expected to see (and did see up until i patched to firefox 25):
User-Agent: light owa plz
