Recently ( in the last week) Thunderbird has gone from starting almost instantly to taking over thirty seconds to start (show a gui).
I have tried uninstalling Thunderbird (as well as hidden profile directory) and reinstalling and starting again from scratch but still slow to start.
Have tried starting with all plugins and addons disabled but still slow.

Anybody else see this?
Plasma 5.8.6
Thunderbird 52.1.1
