693252 - Disabled plugins are enabled falsely on environment change

Status: RESOLVED DUPLICATE of bug 698324

(Core Graveyard :: Plug-ins, defect)

Description

[Michiel Hazelhof]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:10.0a1) Gecko/20111009 Firefox/10.0a1
Build ID: 20111009031012

Steps to reproduce:

I use a synctool to keep my firefox & profile in sync across multiple machines (all win7 x64, exact same firefox and profile location).
I disable some unneeded  plugins (java, word etc), close firefox and wait for the other machine to sync.
-profile is used to specify the profile location, everything else transfers fine.

Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:10.0a1) Gecko/20111009 Firefox/10.0a1 ID:20111009031012


Actual results:

The plugins were enabled again.


Expected results:

They should be disabled (I guess using some kind of blacklist)

Behavior like this is since Ages, presumably on all Gecko/Toolkit Apps.

Thunderbird indeed has the same behavior (so I guess other gecko/toolkit to I guess), but I guess this would be a nice fix since enabling plugins when the user thinks they are disabled is a security issue (in my mind at least).

This happens to me intermittently when Nightly builds auto-update on my Mac. All my disabled plugins will sometimes be enabled silently.
