Mozilla Thunderbird

[FourWheelDrift]

I've tried searching the Thunderbird forum but the search criteria I need seems to bring up lots of unrelated items to wade thorugh I wondered if anyone might know on here.

In Outlook () I used to be able to switch off the "read mail" option on new emails, keeping them bold and 'unread' until I chose to change them to 'read' myself.

Thunderbird changes my emails to 'read' as soon as I click on them but if I want to action them later I have to keep remembering to mark them back as 'unread'

Is there a way of turning this off in Thunderbird, the only option I can see is to mark the message read after x secs, I could set this to 9999999 seconds but it seems an odd way to do it.

Thanks
