I am currently running Thunderbird version 128.11.0esr on Windows 11 on a Dell desktop computer.

I have been running Thunderbird for years. But back in February 2025 my previous Dell desktop died, so had to purchase a new Dell desktop running Windows 11. Then I downloaded Thunderbird and installed it on the new desktop then copied over the profiles that fortunately had been backed up just a week prior. It has been working fine. (When I installed the Thunderbird on the new computer I did not realize there was a difference between ESR (Extended Support Release) channel and Release channel; I just downloaded and installed what I came upon.)

However, around 5/28/25 got a pop-up message that stated something to the effect it is recommended I upgrade to Thunderbird Release.

Should I download and install a new Thunderbird from the Release channel? Will the existing profiles work with the Release channel Thunderbird? Thank you for your help.

Upgrading to the Release Channel is optional. You'll still get security updates and bug fixes if you don't update. Your existing profiles will work with the Release channel. Consider the following to help you decide.

Release Channel:

- less stable

- newest features

- other improvements, e.g., graphical/functional

Note: some add-ons will not work until they are updated.

Extended Support Release Channel (ESR):

- more stable

- consistent behavior

- low maintenance

- fewer new features
