Firefox OS 1.2 and UA override settings

[Karl Dubost]

Jim,

So I updated the device to 1.2 today
It was said in another thread that to cancel the UA override, you could set:

general.useragent.updates.enabled to false


My issue is that both in
/system/b2g/defaults/pref/user.js
/system/b2g/defaults/settings.json

there is NOT such a preference.

1. If not here, means true, do I add it to user.js or to settings.json?
2. If somewhere else, where is it?

OK. I have figured it out and tested.


1. Testing a domain with UA override on
Getting mobile site

2. Putting the preference to "false"

→ adb pull /system/b2g/defaults/pref/user.js b2g-user.js
51 KB/s (1859 bytes in 0.035s)
→ grep useragent.updates.enabled b2g-user.js
→ echo 'pref("general.useragent.updates.enabled", false);' >> b2g-user.js
→ adb shell mount -o rw,remount /system
→ adb push b2g-user.js /system/b2g/defaults/pref/user.js
137 KB/s (1909 bytes in 0.013s)
→ adb shell mount -o ro,remount /system
→ adb shell stop b2g && adb shell start b2g

3. Testing the same domain after erasing cookies.
Getting the desktop site.


I will update the script mozua.sh to take into consideration b2g 1.2+

Hi Karl,

The default prefs are set in Gecko here,
http://mxr.mozilla.org/mozilla-central/source/b2g/app/b2g.js?rev=b843867654c3#764

To change the default, I think you can add the new pref to either
user.js or settings.js (or try adding to both).

Note that "general.useragent.updates.enabled" only applies to
overrides through *updates*, overrides through old-style prefs are
independent and still controlled by
"general.useragent.site_specific_overrides".

Cheers,
Jim
