This is the only page-reading TTS that works for me (five-stars for that). FF 60.0.2. The only options I think the add-on needs for becoming five-stars are stop, pause, resume, speed up. An option to change voices would be a nice plus. Oh. The computer reader is way too dang slow for me. No way I read that slowly. Is brutal to listen to while following along. And unless other add-ons I have are conflicting there isn't a way to pause. If I get interrupted by someone walking into my office there isn't a way to politely pause and shift attention to the human. The add-on continues to drown them out unless I silence my speakers. But hey...at least the add-on works.
