Just finished helping my grandfather solve some of his issues with #thunderbird. He didn't know how to create lists of contacts. I quickly set this up and closed maybe 1000 tabs (I don't know how he opened that many). I was also surprised to see he still uses #Firefox, although all his extensions were gone. Reinstalled #Bitwarden, #uBlockOrigin and #istilldontcareaboutcookies. Now he's fully open sourced again. He even mentioned that he thought about sponsoring Thunderbird.
