If you select a chunk of text in the page and right click there should be a context-menu option to translate the text. It's a popup with a textarea and not in-situ, but it's the same local model as far as I can tell
> By contrast, ex situ methods involve the removal or displacement of materials, specimens, or processes for study, preservation, or modification in a controlled setting, often at the cost of contextual integrity.
Might as well use the correct words if you want to talk above people's heads.
First: No need to be rude, "in situ" is a very commonly used phrase among English speakers, as should be evident from the Wikipedia article [1] you yourself cited
Second: The normal Firefox translate feature replaces the text in the page with the translated text - retaining its styling, position, context w/ images, etc. The right click menu, does not. I described the right click menu as "not in situ" which is correct.
