706053 - changes to default preference branch doesn't persist

Status: RESOLVED MOVED

(Firefox :: Settings UI, defect)

Description

[Xiaoyi Shi]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:8.0) Gecko/20100101 Firefox/8.0
Build ID: 20111104165243

Steps to reproduce:

As a bootstrapped extension can't have its prefs.js, so I tried to set up defaultBranch in bootstrap.js::install(). And retrieve the value of the specified key in next browser session.

Here is the code:
Services.prefs.getDefaultBranch('extension.bootstrapdemo.').setBoolPref('installed', true);



Actual results:

The 'extesnion.bootstrapdemo.installed' is gone after reboot the browser.


Expected results:

'extesnion.bootstrapdemo.installed' should persist after reboot.

The default branch was never meant to be persistently modifiable. Though as legacy extensions are no longer supported this bug is no longer an issue.
