The PDF reader is considered an internal component of Firefox, so extensions are not allowed to inject scripts into the page. If you have a translator extension that integrates with the right-click context menu and is designed to grab the selected text, that still should work.

but it seems i can't use ff anymore. unfortunately non of extensions don't work via right-click options , or i cant find.
