I have standard Thunderbird installed in the standard location on my C: drive.
I just created a fresh install of Thunderbird Portable on a thumb drive using the PortableApps app.
Before creating ANY account or profile information, I navigate to /// -> Help -> Troubleshooting Information.
I see that the Update Folder parameter is pointing to a directory in C:\ProgramData\Mozilla\updates; this is NOT portable.
Clicking on about:profiles, I see Root and Local Directory parameters for a non-default profile that are pointing to directories for my standard installation.
When I REMOVE these erroneous references, Thunderbird Portable DELETES the references from profiles.ini on my C: Drive!!
W.T.A.F.?? Why is a portable app modifying files on a non-portable drive??
I've done this twice now: uninstalled completely. Reinstalled. Same thing. I ultimately set my profile.ini to read-only so it couldn't be edited, which causes TB Portable to issue an error.
Please advise.
