Hi, thanks for the feedback. Luckily this can be worked around:

1. Open the addon's popup (click the Mark My Search icon in the top-right, or if it's not there, find it by clicking the jigsaw button).
2. At the bottom, click Highlight.
3. Under [Sites to Not Detect As Search Engines], type "translate.google.com", then close the popup.

Hope this helps!
