Google had removed extension from webstore, and I don't care enough for now to argue with support about it. Maybe one day, when I enhance rikaigu to the degree I was planning...
Enhanced version of rikaikun - translate Japanese by hovering over words. Now with banana flavor!
You'll need make, curl, python, python-lz4 and clang >= 8.0.0. From repo root execute:
rikiagu/$ makeThen you can 'load unpacked extension' from Chrome.
