Translator for Microsoft Edge

The extension does its main job properly, at least in my use cases, but causes problems when typing, especially when posting replies under Facebook comments. I suspect it interferes with spell checking, and even the copy/paste feature. I often get duplicate sections of my text, when I paste. i.e. a paragraph above the content I copy/pasted.

can't recover the original text once translated.

The translation is very fast and accurate. There are many choices of target language, which makes it very useful.
