I love it, but - when you hover with your mouse over big chunk of text, the translating window pops up to fast(it is being activated by every piece of text that i hover over while moving to the exact word i want to look up), this makes it harder to point the right word, because the pop up covers large areas of the page. IT WOULD BE GREAT IF WE COULD SLOW DOWN THE FEEDBACK FOR A TINY BIT, OR ACTIVATE THE POP UP MANNUALY AT WILL. THANKS

Still lacks some of the nice features of the Firefox version, like being able to easily create word lists for studying, but it's far better than using a separate dictionary website.

Loved it back when I used Firefox, and the port works like a charm in Chrome. Kudos!

This is a very useful extension, but there is one frustrating glitch--if there is any bold text immediately before a kanji compound you want to highlight, the extension won't work on it.

It is not working for me. It did some months ago, but at some point, it failed and now it won't start. I click on the icon, and after a few seconds, the extension crashes and I get a Chrome message asking me if I want to load it again. I've reinstalled the extension and even Chrome, with no luck :(
