So you like my blog and you want all the latest articles to come in automatically in Thunderbird? That’s do-able, just follow these steps:
Open Thunderbird and go to Tools > Account Settings.
Click the Add Account button at the bottom of the window.
Choose the RSS News & Blogs option and click Continue.
You can choose to name the account, if you wish, (the default is News & Blogs) then click Continue.
Double check your account name and if it’s correct, click Done. At this point, Thunderbird will take you back to the Account Settings page.
Click on the name of the account you just mad (News & Blogs).
Click on the Manage Subscriptions button
Now, since you want to add my blog to your subscriptions, click the Add button at the bottom of the window.
This next little form asks for the blog feed. The feed url for this blog is: https://tbirdhowto.wordpress.com/feed/. Cut and paste that address into the Feed Url field, and click OK. My blog name should appear in the Subscriptions window. If it does, close that window to return to the Account Settings page.
Now click OK to close the Account Settings page.
You should see in your folder pane, at the top, a new folder called News & Blogs (or whatever you named it). If you click on the arrow (or plus for Windows) next to the name, it will show you the blog feed name. Click on that, and it will show you all the articles that Thunderbird downloaded from the blog. Keep reading if you’d like details about what you just setup.
