Start on Windows start-up
How come there isn't a setting to start Thunderbird on Windows start-up? Other relevant e-mail apps seem to have such a setting, which is logical, as the e-mail app is something many people want to have on all the time.
Having to google how to manually add apps to Windows start-up folder in 2024 feels silly, and might even be too much to ask for some users who aren't "good with computers".
There's a reason why most relevant apps have such a setting, and that reason applies for Thunderbird aswell, so stop being stubborn and conservative and get it done.
