Problem you are trying to solve

Added "Check for Updates" feature in Thunderbird Android。When you check that there is a new version, you can directly click Update. Firefox android doesn't have an update check function, and then if I want to update the new version of Firefox, I have to go to google play to download the update, but I'm in China, and I need to use a vpn to use Google play, which is very troublesome, so in order to avoid this from happening to thunderbird, I need to add the check update function

Suggested solution

Thunderbird needs to automatically detect updates like Firefox windows and download updates if they are available ...
