In Ubuntu 22.04, I want to stop Thunderbird from updating due to this bug which prevents access to MS 365 (needed for my professional email). I followed the instructions and downgraded Thunderbird to an older version, but it still updates automatically to the most recent version every day.
Yesterday I tried to follow this answer, using the about:config method to disable app.update.auto... But today it went back to the most recent version again, so this is not working.
I'm confused how these updates happen: are these regular updates from Ubuntu or specific to Thunderbird?
How can I disable Thunderbird updates?
