I do not think it very practical having to select a word and then move the mouse cursor up to the addon icon, just to open a translation pop up. I think it would be more desirable to be able to select a word and have a pop up appear right next to it. The plugin is otherwise OK.

On clicking the button, the to-be-searched word shall be read from the clipboard, not least for I use the "copy on select" add-on. That would make for easy workflow. Auto-bookmark function (with bookmark management and/or integrating in Firefox bookmarks) is missing, for I tend to forget words I looked up (in other words, automated bookmarks would be best for studying). Neither "Pocket", that is now integrated in Firefox, nor the "traditional" bookmarks in Firefox are workarounds since Linguee opens in a little window that cannot be bookmarked :(

A Bookmarklet serves my purpose better, minus I've yet to figure out how to add bookmark functionality. Here it is:

javascript:term=window.getSelection();if (term=='') term=prompt('Look up on Linguee:'); if (term) void(open('https://www.linguee.de/deutsch-englisch/search?source=auto&query='+term,'',''))

If you want to use it, make a random Bookmark, click on its "preferences" and replace the URL with the above. To alter my version to your favorite lookup site, replace the URL in the line. Hugs

That would be nice to have a shortcut; The pop up widow should directly fit the translated words. I have to scroll to go directly to the most important information
