Which "search box"? Not in Ctrl+F Nor in address bar then, Where?

Just remove the extra SIGNS +word+word+ if not it is useless.

Erster Eindruck:
sehr praktisch, gute Ergebnisse

Exactly what I wanted ! But indeed '+' character between lines are annoying

Would be perfect if it would not add additional characters as "+" between words.

The idea for this add-on is great! It would save me the hassle of calling up the website and speed up the translation process.
Unfortunately, when the text is transmitted, + characters are placed between the words. This would turn the previous gain in time into a negative.
It'd be great if you could fix it. Thanks a lot!

Adds a + sign in front of every word, making translation unusable. FiFo ESR v52.8.0 for Mac.

ok but too simple
