I recently upgraded from Thunderbird portable version 60.0.1 to 91.6, using it standalone, no platform.
I have been trying to get to see my sent emails in conversation in Thunderbird. The Thunderbird forum has been advising me via a thread I started.
It turns out there is a context menu option, "Open message in conversation"

I always assumed they were the exact same versions functionality-wise as the corresponding non-portable version, but is this not the case? IN that case, was there a reason this menu option was left out?
Many thanks!!
