Question

When a user adds our addon to their browser (firefox) as the browser restarts we would like it to run the function whats_new()

Where do we put the code for that?

Or in other words, is there some way I can run whats_new() as my plugin is loaded in Firefox?

Thanks!

Short answer:

Longer Answer (with history):

That URL describes the “app-startup” which I think is exactly what you want … and it’s no longer supported 🙁

However, as this URL explains:

there is now an alternate way of doing something similar, using the “profile-after-change” category.
