Hi. I installed a new Ubuntu version (20.04) and re-imported a saved profile. Then, I copied all files from the all profile into a newly created one. However, when I startup thunderbird, the old profile is not loaded and a new one is created. Also when I directly define the Profile to use at startup (via -profile PATH/TO/PROFILE), it is not loaded. Instead, the following warnings shows up: `1601742210216 addons.xpi WARN Not converting unknown addon type undefined` `1601742213947 addons.xpi WARN Can't get modified time of /usr/lib/thunderbird/features/wetransfer@extensions.thunderbird.net` Thunderbird then starts with a new empty profile. How can I recover my old one?
