Thunderbird mark message as read after reply
Well it appears I am not the only person having a problem with thunderbirds marking emails as read.

This is how I use thunderbird
I have disabled the “Automatically mark message as read” functionality so that I have to set messages as read. If I don’t do this many emails were being marked as read when I hadn’t really finished reading them or replied to them.
In my case I classify an email as read when I have replied to it or clicked the read button (they require no reply)
I just want Thunderbird to set the read flag when I reply to the email.
Also I normally view the email in the “Message pane (F8)”
After installing

I get exactly what I want. Thunderbird now sets emails as read, when I reply to the email.

i don’t understand how to install this so that Thunderbird gives me this new option for marking messages as read after i reply.

Download the https://nic-nac-project.org/~kaosmos/changequote-0.7.4.1.xpi file and install to Thunderbird (via addons and select the “install from file”)
Then go to the Addons and select the “Change Quote and Reply Format” Options button. You then select the 3 tab and select the “Mark message as read after reply”

Thank you!
I know it’s a really simple thing but it makes the Thunderbird experience that bit better

This was a problem wich I had with Thunderbird/ Icedove.
Installed the add-on and it does what I need!
Great, thanks!
