I don't understand this... Rikaikun doesn't work at all! Nothing happens when I hover over Japanese text. No pop-up definition or reading, no text-to-speech, even though I enabled it in the Extension options. I thoroughly examined all the settings, and they remain default except for these: I've selected "On click" for site access, I've pinned the extension to my toolbar, I've enabled text-to-speech. It used to work well when I installed it the first time, but then it stopped abruptly. I removed it and tried reinstalling it to see if the same thing would happen again, but it didn't even work at first this time. I don't think the changes that I've made could interfere with the extension's functionality, and I've turned off my one other extension (I don't know what else could be interfering). I've tried using a shortcut to activate rikaikun; as I expected, it changes nothing. I'm really not sure what else the problem could be because I made sure that I didn't accidentally use a shortcut. I've looked at other similar extensions like yomichan, yomitan, and rikaitan, but I was hesitant to try them because my experience with rikaikan. I very breifly installed yomichan since I read only good reviews. I couldn't customize it before using though, like I can with rikaikun (which is much more straightforward), so I immediately removed it. Has anyone solved this problem or figured out the cause? Is there anyway I can fix this? I have even tried highlighting the text instead of just hovering over it. Could it be an update that I haven't installed yet for Chrome( There is that...)? :( (TLDR: Rikaikun is not working at all (legit) and i can't find a cause or solution. It is very frustrating because the extension is practically useless this way.)
Hello Extension Creator, wouldn't it be possible to use an AI API to translate the text into other languages?
I love it, but I can't find a way to make it start when I start the browser.
Could have more languages besides english. I have to use the translator anyway, so it's not useful.
Doesn't work at all...But maybe we need to do something about settings but not information about it so useless.
要是能有日语的解释（而不是英语）就好了，更贪婪地说，想要可以导入辞典的功能
We need Chinese. 我们需要中文。 中国語が必要です。
I have to click the icon every time to turn it on. Can it automatically turned on or always on? 每次都要點圖示才能啟用，可以一直開著嗎?
This extension is perfect but I notice some bugs: 1. It gets on the way whatever japanese text I am typing exp when the cursor is near the text 2. It often turns on the "hide definitions and show only reading" by itself. It's not like there is shortcut to it, right??
Love the app. but keyboard shortcut without clicking the icon would be super useful. Thank you.
