Hi,

Thank you for your report! I’ve uploaded a new version (v1.0.1) that should fix this issue. Please make sure to update to the latest version. The problem was that Firefox doesn’t allow certain characters in the filename of downloaded files, so I’ve adjusted the addon to remove them.

As for season downloads, this feature isn’t implemented yet. I need to prepare a few other things before adding it. I apologize if the addon is lacking in some areas—it’s just a hobby project, and I don’t have much time right now. However, feel free to suggest new features or report any other bugs—I’ll do my best to address them!

Kind regards
