Having been a long standing fan of Portable apps and Portable Thunderbird, I now find that it is crashing all the time.
It is the latest version (sorry, can't fell you which one it is since it is freezing shortly on loading).
I admit, the overall size of the application has increased to 4 GB since I move all the IMAP folders into a local Thunderbird folder that serves as my 'store' of emails on my SD card (leaving my IMAP email with more space).
I don't know what I am doing wrong.
Besides, am I right in reading that Mozilla have now discontinued support to TB?
What portable email client do I migrate to, in that case?
