本当に素晴らしいね〜
Extremely useful! For someone who has to deal with japanese and isn't native, it is a must have extension. It consumes a fair amount of RAM (about 200MB I think) so it may not be wise to use it in a very old PC. If you don't activate highlight text boxes in rikaikun settings, it may be a little buggy when you try to use it in an input text box. If it doesn't translate, you may have accidentally pressed some shortcut like "D" (it hides translation and leaves only the hiragana pronunciation). Cons: - Doesn't work in some pages. - No font size option. - Very few customization options.
it doesn't working,why?? please help!
Saved my life in japan
非常不错
Really helpful.
I like it a lot, but like Ola Nordqvist said it is becoming really annoying. My mouse is not even near a word and it just randomly highlights a word. lately i have been turning it off because it will delete my word/sentence. Not sure why, but I don't remember raikachan for firefox doing this. Please correct this issue.
its helping me quite a lot when im trying to read webpages in japanese.
I use it in Chromium for Ubuntu. It works nicely, and it's a very useful dictionary when reading websites in Japanese.
¡Me encanta! Me ha servido muchísimo para aprender vocabulario.
