Current Thunderbird Very Slow to Load

On several machines running current manjaro/thunderbird, thunderbird has abruptly become slow to load. It seems to hang on:

[Pop3ModuleLoader] Using Pop3Service.jsm

Below, the first output is made with my .thunderbird directory:

[jake@P3 ~]$ thunderbird

Below is output with a fresh .thunderbird directory. Both outputs reflect the same slow loading speed:

Considering that thunderbird is actually firefox in disguise, perhaps it’s related to the xdg-desktop-portal-gnome bug. Try this… :arrow_down:

sudo pacman -R xdg-desktop-portal-gnome && sudo pacman -S xdg-desktop-portal-gtk
