Language Browser Plugins

Perapera-kun 2.0 Live

Well its finally released. Here is the new version of Perapera-kun for Firefox. Took a bit longer than I was hoping but I am now happy with what is released. I submitted it to Firefox but they always take forever to actually update it on their site so it is available here first for anyone who wants to try it out. You can find it in the download box in the left or find the direct links to the file at the end of this post. Here are the new features:

  • Wordlist Sidebar: Press ‘S’ while displaying an entry to save it to the wordlist. (Also is a “Grab Entries!” button, but more about that in a later post. Stay tuned.) You can add, delete, and export these entries to a file whenever you want.
  • Japanese and Chinese united: Now both Japanese and Chinese are handled in 1 plug-in by adding the dictionaries you want.
  • Korean support coming very soon! Currenty it will display the romanized pronunciation but I dont have a dictionary to use yet. Can anyone help?
  • StatusBar Icon: Now everything is easily controlled via the Perapera-kun status bar icon. Enable multiple languages with one click, options dialog, and more.
  • New Chinese-English Dictionary: I now use the open public CCEDICT to feed the entries for Chinese-English. This should fix alot of the inconsistencies the previous dictionary had.
  • Chinese-German Dictionary: Uses the HanDeDict open public dictionary for Chinese-German. Please only install 1 Chinese dictionary at a time.
  • Supports Japanese to English, French, German, and Russian dictionaries along with the Japanese Names dictionary compiled by
  • Redeigned options dialog that is cleaner and easier to use.
  • New icon for the add-on

After you download the add-on you will need to install the dictionary add-on for the language you want to use.  For Japanese, visit to install one of those dictionaries and for Chinese, download the English or German dictionary in my download box or in the links below. Thanks for using and I look forward to your feedback.

New Features for Perakun?

Great work. I was just thinking today that you promised an update but was thinking you must be very busy settling in Japan.

I’ve installed 2.0, and now I cannot ‘turn on’ the Perapera-kun icon on the toolbar. I’m on FireFox 3.5.5. With Perapera-kun 1.0, I didn’t have this problem. Any suggestion on how to debug this?

Arnaud November 26, 2009 at 9:22 pm

You should see a little star in your status bar. That is where it leaves now.
Don’t forget to install dictionaries.

taroikai November 27, 2009 at 10:12 pm

Thanks, Arnaud. I hadn’t noticed the icon in the status bar. Now it’s working.

A couple of comments on 2.0:
1) The new color scheme for popup makes text slightly harder to read.
2) The old Perapera-kun toolbar buttons are still available. What do they do?
3) It’s unclear how to display the help popup for the keyboard shortcuts.
4) Depending on the screen resolution (or size?), the popup covers the relevant source text.
5) I find the ‘N’ and ‘B’ buttons really useful. Great work, and thank you.

I’m using Firefox 3.5.5. I’ve installed Perakun 2.0 and the CEDICT dictionary 1.0. I can click on the yellow star at the bottom of the firefox screen. I can secondary click and get a dictionary window. But there is nothing in the window and I can’t get any pop ups working. I’ve tried alt-ins which appears to be the default to start Perakun but that doesn’t work either. Please help.

But, I’ve been dying for the korean version for sooo long. There are some great dictionaries, I’m sure. Good luck

Hi Jack. Thanks for the comment! After the new Japanese plugin and Chrome are done we want to do Korean. Hopefully a 1.0 will be out early next year.

numblest November 18, 2009 at 5:45 pm

This is great! Any word on how often you’ll update the dictionary files?

la mogura November 18, 2009 at 5:52 pm

The CCEDICT gets updated nearly everyday, so if you see any mistakes you can submit corrections here: I will probably update it around every 3mos, its really easy for me to do so now, so its just a matter of when theres enough changes to warrant an update.

Fianlly, an update. Thanks so much for this great extension. I’m just curious though, can I now uninstall Chinese-perakun now that you have the Chinese-Eng-Dictionary extension?

la mogura November 21, 2009 at 2:54 am

Yes please uninstall Chinese perakun, don’t really need it anymore. Enjoy!

I love the plugin, thanks a lot. One thing i was wondering is can i set it to automatically be turned on and set to japanese instead of having to click the star icon and switch to japanese every time i open firefox? I use firefox solely for japanese stuff, and a different browser for english stuff.

tehyoshi December 27, 2009 at 11:37 am

Oh wow, I can now have the option of just traditional characters displayed instead of both traditional and simplified Chinese! I love this!

I really can’t wait for Korean to be implemented!

kyleintaiwan January 25, 2010 at 6:15 am

Have used peraperakun for a while, now. I think it’s a great extension, and i have no problems with the changes you’ve made.

However, on the last upgrade, the wordlist feature seems to have been broken. In fact, i can’t use any o f the hotkeys at all.

This is particularly big bummer, because i really, really liked the introduction of the wordlist.

I run a debian system, with iceweasel. Stock Lenny, on an intel 64 dual core kernel

AAAAAAAGUHGU! I keep waiting for a korean perapera and checking this site….months go by…I’ve been waiting too long……. 🙁 🙁 🙁

admin March 23, 2012 at 1:24 pm

Hi Jack. Sorry about the long wait. We hope to be able to offer something in the near future but I can’t say exactly when that will be. Thanks for your patience.

Guest November 30, 2012 at 11:08 pm

I was wondering for a long time about the announced Korean Pop-Up dictionary. This would be really helpfull. I know I have no right to push you or to complain, so please just understand this as a note of interest. Thanks for your work.

Janelle January 17, 2013 at 5:41 am

Can you guys give any kind of timeframe for when the Korean Pera Pera Kun will come out? Like many others I’m dying for such a version.

admin January 17, 2013 at 10:01 am

We are sorry to keep you waiting. We also want to use this. Is there a good dictionary? We haven’t found one yet.

Ginobili June 9, 2014 at 7:04 pm

For the past few years I have been periodically checking this page for the Korean popup, is it still in the works? Please understand that I have no right to complain, it is just that I would really love to use it for my study. Thank you for your work, I love the Japanese plugin and have been using it for years.

My little star disappeared. Oh where, oh where did my little star go? How can I turn you on, if I can’t see you Perakun?
