Thunderbird Email Hacks

Disable Sort View by Threads

I found this option is available through advanced configuration. Here's a quick guide:

* In Thunderbird, go to 'Tools' .. 'Settings' (not: 'Account settings')

* Scroll to the bottom and click 'Config Editor' button

* In the box, type 'mailnews.default_v'

* Below, click the pencil ('Edit') button next to 'mailnews.default_view_flags'

* Change the value from 1 to 32 (also set to number)

* Restart Thunderbird.

All your folders should now be sorted unthreaded.

Disable Updates

== DISABLE AUTO UPDATE VIA "REGEDIT" IN WINDOWS: ==
In windows, if you want to make sure, Thunderbird app update is  completely disabled, then for both 64bit & 32bit Windows or TB,  follow below steps:

* runregedit.exe, ( reg =registry ) , accept the RISK related warnings, 
   and find/browse to below reg key location:[[BR]] 

HKEY_LOCAL_MACHINE\Software\Policies\Mozilla\Thunderbird 

or

HKEY_LOCAL_MACHINE\Software\Policies\Thunderbird

HKEY_LOCAL_MACHINE\Software\Policies\Mozilla\Firefox

If any one of the above/below (Thunderbird related) reg keys does not exist
in Windows Registry,then Create them with a right-click on  the previous key
(for example: "Mozilla"), and then selectNew>Key> specify key name 
(for example: "Thunderbird" or "Firefox"), then right-click on the key Thunderbird
to configure TB, or, right-click on key Firefoxto configure FF ,
and again selectNew>Dword(32-bit) Value > 
name it DisableAppUpdate

set its value to1
to disable TB/FF app update & auto-update.

( If later you want-to/need-to enable app update, then you may set!DisableAppUpdatekey value to0. )


 * After above setting is done, user will see a line[[BR]]'''''"Updates disabled by your system administrator"'''''

reg add HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Thunderbird /v DisableAppUpdate /t REG_DWORD /d "1" /f
