I used to think that paying money (let alone, paying €10) for _a browser extension_ isn't the wisest thing. So OK, I bought it eventually but what do I see? It's not possible to add a translation to a words list because of a glitch: clicking the 3 dots inside the translation pop-up has absolutely no effect in every Firefox version I use. It works properly only as a stand-alone app in macOS. I see my synced words lists but no way to add words to them. The menu elements either appear dislocated on the left of the browser's window or don't show up at all.

Update. It doesn't work on such comment section as Disqus. Neither clicking nor highlighting and selecting Mate Translate from the context menu does anything.

Fix that, please.

Update March 7, 2021. Still not fixed after the latest update.
