Rikaichan loads a lot faster and can be enabled with a context menu entry.

Extremely helpful for studying and navigating japanese web pages! Helps immensely when you forget that one kanji you need to know.

It's alright. Doesn't show all the definitions of a word and has trouble figuring out words without kanji/problems figuring out where one word ends and another begins. Nowhere near as versatile or full of features as Firefox's rikaichan. This extension is just a bare minimum copy paste job, even after all these years. :/

I cannot activate it at all, it doesn't work unlike rikaichan which I don't have any issues with.

It doesnt work on my device. I think the options should show to activate it or not because I cant activate it by clicking it. Or it shows that it's activated and still wont work. I heard a lot of positive stuff about it but when I cant use it because something doesnt work then I can only rate it negatively. It should be fixed somehow because I think then it will be really good.

It doesn't work for me. I much prefer the Firefox version, Rikaichan. I finally looked at the Support tab and realized that it's because I have uBlock on! Wish I didn't have to choose one or the other, but I'll work around the issue until there is a solution!
