Could you elaborate on the work spaces? Containers? It works across multiple windows but for containers i dont think it would as they arent meant to share. For disabling/uninstalling i believe thats default behavior for firefox. You need to wake the tabs before uninstalling or disabling. I'll look into adding something that can handle this better though. More info would be great if you could send an email, open issue on Gitlab or discord? :)
