Thanks for the feedback! I didn't even realize that comments weren't working on my site because the captcha wasn't showing up. Apparently it has been like that for months so I'm glad you brought it up here.
Firefox has strange behaviour where the translation wouldn't show on the DeepL tab unless it was an active tab, but I think I found a better workaround for it rather than having it show in a new window's tab. I'll release this new version soon (0.0.6).
