I prefer push notifications, and having recently downloaded Thunderbird, I went to the server settings after adding a Gmail account. However, I can't find any option that seems to enable push notifications, only polling rates.
So I have three questions:
Does Mozilla Thunderbird support push notifications, with or without an addon?
If it supports this without addons: Under Account Settings > [account] > Server Settings > Server Settings, it gives the option, "Allow immediate server notifications when new messages arrive". Is this the option to enable push notifications, or is this something else entirely?
If it supports this without addons, If the answer to #2 is "No": How does one enable this function?
