FossaMail doesn't provide the same option when following the equivalent path within the program.
My suggestion is to create one.
It'll be obvious to users of Pale Moon and, historically, Firefox, where to check for the availability and find the latest update within the context of the program itself.
Right now, I'm not sure if there is an update mechanism within FossaMail or not. If it's there, it's non-obvious to me, which means it may be non-obvious to others. I knew to look for an update because I read a thread here that said there was one- but not everyone is going to always be checking the forum to see if there are updates available. Also, I wound up going straight to the file and downloading it and running the install program, which is a good option to have, and it was fine with me, but that's adding another layer of things a lot of PC users aren't used to doing, that may keep some users from running the safest most secure up to date versions of FossaMail. Obviously, adding an update mechanism like the one in Pale Moon wouldn't keep those who want to from installing updates from a file they download as they do with FossaMail right now- it'd just provide an extra option.
One principle of UI design is usually minimizing the number of steps a user has to do to get from the first step to the final step, because some users give up or get distracted at each step, meaning you reduce the number of people who actually get the task done the harder something is to find and the more clicks it takes to do it. And adding "check the forum", "go to a website", "find the right files", "download the files", and so on and so forth before you even get started trying to apply them within the program is a lot of extra steps.
Similarly, Lightning doesn't update through the add-on updater when you click "Check for updates" (Or at least isn't as of the time I'm typing). It says none available, even though one obviously is. So I manually downloaded that through the website also, and I'm still working on figuring out how to apply it [Figured out how to do this and did it, but my suggestion still applies
Just a suggestion obviously.
