I have a few feeds configured into Thunderbird but wasn’t reading them very often, so I “disabled” them to load manually. Despite this it tries to contact the sites often and, when not able to (firewall) goes into a frenzy of trying to contact them. All this despite being disabled. Disappointing combined with the various update sites it tries to contact every startup, which is completely unnecessary as well. Couple of times a week should be the maximum rate.
