I’m on a GNU/Linux system (Pop_OS!) and I have Thunderbird installed

via the apt system package manager (.deb).

System package manager install.

$HOME/.thunderbird/

Snap package manager install.

$HOME/snap/.thunderbird/

Your Thunderbird email filters are located in this subdirectory

(msgFilterRules.dat).

Vim Directories.

I’ve created subdirectories within $HOME/.config/ as a

place to store my vim sessions. You may not have these directories on

your system, but you can create them using the mkdir

command.

$HOME/.config/vim/sessions/session-files-here.vim

Vim session file.

I’ve created session files for purposes of editing my Thunderbird

email filters. This session only stores the shortcuts needed to make

flawless edits to my email filters. I will share them with you.
