720337 - prioritizing of plugin based on the modified date instead of its location

Status: RESOLVED WONTFIX

(Core Graveyard :: Plug-ins, defect)

Description

[vishwa]

User Agent: Mozilla/5.0 (Windows NT 5.1; rv:9.0.1) Gecko/20100101 Firefox/9.0.1
Build ID: 20111220165912

Steps to reproduce:

I created a plug-in of xyz mime type and placed in the plugin folder. There was already 
plug-in of same mime type (xyz) whose entry was in the registry.


Actual results:

Instead of using my plug-in, firefox loaded and used already existing plugin of same mime type.


Expected results:

Based on the MDN documentation, firefox searches first in plugin folder and then the registry. 
https://developer.mozilla.org/en/Gecko_Plugin_API_Reference/Plug-in_Basics#How%20Gecko%20Finds%20Plug-ins

But if there are two plugins of same MIME type, one in plugin folder and another in registry, then the plugin which is in plug-in folder has to be given highest priority. When I debugged the firefox code, i found that though firefox searches as per the details gives in MDN, but loads/lists the plugin based on the modification date of a plug-in which is a bug as per the MDN documentation.
