Thank you very much!

On my Mac with Firefox 41.0.1, I have not been able to get this plugin working at all. Sometimes it says that it could not be verified. But when it doesn’t say that, I still can’t get it to do much. First, when I try to enable the plugin, I have to click OK to load the database, etc. Fine. But nothing happens other than showing the box saying that Perapera Chinese is enabled. That box never goes away on its own. The Perapera Chinese icon never lights up. I got it to work once, last night, showing definitions in a popup, but only for a few minutes and never again.

Hi. The current version should be verified. Hope you resolved your issues with this.

guanche October 2, 2015 at 8:24 pm

I’m afraid I have exactly the same problem with this latest update with Windows 7 (64bit) – apart from the fact that I’ve never got it to work.

Firefox version 41.0.1

Francis Campbell October 3, 2015 at 3:44 pm

Delete the plugin and anything else that might be conflicting. Reinstall Firefox. Download the new version of the plugin.

Alra October 3, 2015 at 11:17 am

Hello, the plugin now works for me however in Paper and Sepia theme, the definition text is now white and therefore very difficult to read against the backgrounds and the text color is not changeable in options. I prefer Paper theme but until this is changed I will have to use Charcoal. I am using the Chinese-English dictionary.

One more thing, when I am in options on the dictionary page and I click Download, it opens the perapera site tab in every firefox window I have open instead of just the active window.

I am very glad it was finally verified!

Francis Campbell October 3, 2015 at 3:40 pm

Thanks for letting us know about the text. Will look into that for next update.

kelisi October 3, 2015 at 11:52 am

I downloaded this three times. Where is it? Available for Android mobile?

Francis Campbell October 3, 2015 at 3:36 pm

Available for Firefox and Chrome on PCs, not mobile.

Ian Dalton October 3, 2015 at 1:25 pm

No matter what I set the “Enable mode” to, it acts like it’s set to “current tab only,” and any new tabs I open have it disabled until I click the icon to enable it for that tab too.

Francis Campbell October 3, 2015 at 3:35 pm

Noted. This slipped past us. Will fix this in next update.

Andy October 6, 2015 at 6:08 am

Where can I report bugs? I added a few comments on this page, but some of them have disappeared.

Bastien October 6, 2015 at 11:53 pm

Hey there!
Thank you for making the plugin work again with Firefox!
However the French dictionary won’t show up in the list of dictionaries.
I uninstalled manually the dictionary as well as the plugin itself but it didn’t work.
Eventually, I did a “refresh” of Firefox (cleans up all extensions) and I am still having the same problem.
Am I missing something in the process? In the former versions it used to be ready to use after downloading it.
Thank you so much for your help
Your plugin is the best

Rafael October 8, 2015 at 7:16 pm

I installed it in firefox 41 and windows 7 but it doesn’t work . The add-on manager says “perapera couldn’t be verified for use in firefox. Proceed with caution”.

Francis Campbell October 11, 2015 at 11:30 am

This is surprising. Are you sure you are using the latest version? We have verified it on several different computers with Firefox 41.

Rafael October 11, 2015 at 6:46 pm

you can see here what I can see in my computer when perapera chinese is on and my version of firefox (in windows 7). After installing it again, it told me “a dictionary index needs to be created” but nothing happens and it gets stuck. I don’t know where is the problem. If it is in the dictionary, I don’t know how to download it separately.

Andy October 16, 2015 at 12:37 pm

I’m still getting that here on my Mac, using FF 41.0.2 and Perapera Chinese It says, “Perapera Chinese could not be verified for use in Firefox. Proceed with caution.” Otherwise, it seems to be working, though–as long as I have the Enable mode set to something other than “All browsers.”

guest October 9, 2015 at 5:14 am

Please also update the dictionary database with the next update!!

Mark October 9, 2015 at 2:48 pm

Hi, glad to know Mozilla finally verified the Perapera plugins, my life is complete again. 🙂

A quick question, though—by any chance, have you guys removed translation/translation of loanwords from the dictionaries? In the past I can hover at, say, バームクーヘン and it’ll transliterate it for me (“baumkuchen”), but a few updates back broke/removed this ability.

Francis Campbell October 11, 2015 at 11:29 am

We haven’t touched the dictionaries. I don’t think the dictionary was ever perfect for that.

Mark October 21, 2015 at 2:52 am

Hum! If it wasn’t the dictionaries then I honestly have no idea what might be the cause, but the fact still stands that some update broke/removed this “functionality” (if it ever is). 🙂

Eric October 9, 2015 at 8:34 pm

Hi, Francis! I’m currently using Firefox version 41.0.1 and Perapera, and I’ve noticed that the Perapera plugin can’t read Chinese character in fill in boxes. For example, as I write this comment, I write the characters “你好” but the plugin doesn’t detect the characters. In previous versions, Perapera was able to detect the characters in fill-in boxes like this and the Google translate typing area. Is that a problem with my Firefox or Perapera installation, or has this functionality been lost? Thank you very much, Francis!

Francis Campbell October 11, 2015 at 11:27 am

A couple of people have mentioned this so it looks like it’s a bug.

How do you use that functionality by the way? To check you are inputting the correct characters?

Eric October 12, 2015 at 8:47 am

Thank you very much for the reply, Francis! I use the fill-in boxes for a few reasons: If someone sends me an instant message (not received in web browser) that is in 繁体字, and I can’t read it, or if there is a word I can’t recognize, I will copy and paste the entire sentence or the word into a fill-in box and let the great Perapera plugin help me. Or, as you mentioned, if I am writing something, and I’m not so sure if what I’m writing is correct, I can use a fill-in box and the Perapera plugin to help. For example, if I was trying to write 铁观音 (the tea), but I wasn’t sure how to write it, I would first type it up the way I think it is into a fill-in box and see what Perapera says.

If you need a way to examine the problem yourself, just type or paste a Chinese character into a comment box on the website, and before you hit “post comment”, try to use the Perapera plugin to detect it. If it’s like my computer, Perapera won’t be able to detect the Chinese character(s) until AFTER you hit “post comment”.

The Perapera plugin is fantastic, and it’s made my life significantly easier. If you can bring back the fill-in box functionality of Perapera, that would be fantastic. In any case, the Perapera plugin is great, and you have made my life easier. Thank you, Francis!

Andy October 16, 2015 at 12:22 pm

I’m the same way. I like to be able to double-check my Chinese writing while writing an email or instant message. Hope this can be fixed!

Andy October 16, 2015 at 12:27 pm

I finally got my Perapera plugin to work on my Mac. I just have to set Enable mode to something OTHER than “All browsers.” If it’s set to that, then nothing works at all. (Could that be a bug?) Changing it to one of the other three options fixes it. The “Always enable at startup” option doesn’t actually enable at startup, though. That’s a known bug, I think. If that option is fixed, then I’ll be all set. Until then, I have to enable the plugin whenever I need to use it.

Rafael October 16, 2015 at 3:28 pm

thanks to your comment I was able to fix my problems with the chinese version for firefox. The “all browsers” was in fact the problem and I changed it to always enable at start up. Now it works

GeniusMalignus November 20, 2015 at 11:23 pm

Hi there,

Just wondering about which settings you are talking? I coudln’t find this “enable mode”. thanks for your help

Mik October 23, 2015 at 7:07 am

Nice pluggin but in recent versions there are some webpages (where the product descriptions in where the popup window is showing behind the webpage content instead on top of it so you can’t read it. Using Ubuntu 12.04 with latest Firefox and Perapera. Thanks for all your work!

vncbvbvnnvn October 27, 2015 at 1:27 pm

“always enable at startup” doesn’t work

Can you, please, change position of pop-up to “up” ? (not the “A” button) It will be more easily – to use it with rikaichan.

mabaole October 29, 2015 at 12:13 pm

Hello! First, great add-on, have been using for years.
Using this recent update, chinese version, on firefox 41.0.2.
Just some feedback to help you fix some issues: I have had some problems too lately, would activate the button, the box would appear and not leave, pop-up function didn’t work at all. So uninstalled firefox, a bit of cleaning, installed everything again and still the same.
So I tried some of the solutions in the comments, changing the enable mode to anything than “all browsers” worked for me!
The reading in fill in boxes doesn’t work though and this function was very useful.
Thank you for your work!

pete November 8, 2015 at 8:59 pm

hey guys, any plans to update the cedict database? it hasn’t been updated in almost 4 years…

Thunder November 11, 2015 at 3:23 am

After several years of hiatus in my Chinese reading efforts I find that this is still the only working pop-up dictionary out there. Thank you!
But nowadays Firefox 41.0.2 gives this “could not be verified for use in Firefox. Proceed with caution.” warning. I see that somebody wrote about this for a month ago already, what can be the reason that I’m still getting this one?
One has always multiple anti-malwares going on but still gives you a bit of unease.

Violka10 November 15, 2015 at 6:23 pm

Good day. I have problem with Chinese plugin. I can’t save any words in my word-list. I save a word, it appears in word list, I close the word-list, open again-the word-list is blank, there are no words I saved before. Japanese plugin works excellent, but I don’t know what I should do with Chinese one.

Tadeusz Mollin December 17, 2015 at 5:47 am

Help, it’s Firefox 43.0 now, and Perapera has been deactivated!

Andy December 17, 2015 at 9:48 am

Yep, here we go again.

Andy December 17, 2015 at 10:14 am

I just found a way to fix this. If you feel that you trust all your FF extensions, then you can try the following (AT YOUR OWN RISK) in order to force Perapera to be enabled again.

Go to about:config and enter this in search:

Double-click the value to toggle it to “true.”

Restart the browser.

This worked for me. Hope this helps!

Firefox keeps disabling PeraPera Japanese because it says it’s not signed. Please fix!

Andy December 17, 2015 at 11:48 am

See the workaround above. Hope it helps. 🙂

bob hsiang December 18, 2015 at 3:02 am

Firefox simply will not enable your app. Chrome is my standard now.
