So here is how to configure Thunderbird RSS reader to automatically check for and retrieve articles for any of the subscribed RSS feeds as soon as it is launched :
Browse to the feed subscription which needs to be automatically updated. Right click on it and select “Settings”.
Under the “Server Settings” section, enable the option “Check for new articles at startup”.
From now on, all the messages will be automatically fetched for this RSS feed subscription.
Oh and speaking of RSS feeds, do subscribe to ours here.
