636599 - Firefox Sync should not synchronize "autoscroll" pref (whose default value varies between platforms)

Status: RESOLVED DUPLICATE of bug 636176

(Firefox :: Sync, defect)

Description

[Daniel Holbert [:dholbert]]

Autoscroll is preffed off by default on linux (and other non-mac Unix variants):
> 227 #ifdef UNIX_BUT_NOT_MAC
> 228 pref("general.autoScroll", false);
> 229 #else
> 230 pref("general.autoScroll", true);
> 231 #endif
http://mxr.mozilla.org/mozilla-central/source/browser/app/profile/firefox.js?mark=227-231#227

However, this pref is configured to be automatically synchronized by Sync:

> 981 // Preferences to be synced by default
[...]
> 1015 pref("services.sync.prefs.sync.general.autoScroll", true);
http://mxr.mozilla.org/mozilla-central/source/browser/app/profile/firefox.js?mark=1015-1015#981

...so if you have both Windows & Linux machines connected via Sync, then one of them will overwrite the other's default.  (I just noticed that this pref had magically become set on my Linux machine, after I'd added a new Windows machine (with default settings) to my sync pool).
