a really annoying bug Betygsatt 2 utav 5 stjärnor

EDITED (27 May 2016).

v2.2.6 with firefox 46.0.1

I'm getting the Korpus pop-up window reasonably frequently, when I've just clicked on something i.e. not with the defined shortcut process (which is currently CTRL+select/drag)

This did not happen before v2.2.6

Korpus appears to remember when you pressed the CTRL key, even after you have released it.

This causes all manner of problems.

Any legitimate use of the CTRL key and subsequent selection of text will result in the korpus pop-up. If you select some text (for any reason) then press CTRL then click elsewhere, you get the pop-up


1) select some text to copy/paste
2) CTRL+c
3) position with mouse click to paste
4) you get the korpus pop-up

This is extremely annoying as it is very intrusive and unwanted.

The workround is to amend the shortcut:

1) click on korpus toolbar button - should be set of curly brackets
2) click on little question mark top right
3) change CTRL to CMD (if you're on windows)

N.B. assuming CMD is supposed to be the windows key, this keyboard combo doesn't work at all in the extension, so effectively disables the keyboard shortcut for korpus.

Finally, it would be good if the author provided some means of contacting them, aside from the reviews section.

I'd prefer to work proactively with the dev regarding problems, rather than posting a bad review.




EDITED (19 May 2016).

v2.2.6 seems to have fixed the facebook video controls 'sticking' to mouse problem. Nice.


EDITED (15 May 2016).

I have just discovered a possible bug which appears when using korpus 2.2.3 with facebook videos.

These videos work perfectly with firefox in safe mode.

I have only the korpus extension enabled (all other extensions are disabled) and when I click, for example, on the volume control on a facebook video, the control stays active, even when the mouse pointer is moved away from the video.

It's like the control element remains active after clicking on it.

It appears to be korpus because when I disable this extension and CTRL+F5, the video player controls behave normally again :(

It is very annoying because it makes it very difficult to watch videos.

The video progress bar is also affected. It makes it impossible to re-watch a bit of a video.


EDITED (12 may 2016).

With version 2.2.3, the author has added support for thesaurus.com (use "dictionary.com" in options, then search for "thesarus").

This appears to work fine for me, although I do use NoScript. I must have whitelisted the website when I'd been previously investigating synonym sites.

Please note what the dev says (in the release info), if you experience issues.

I had given my review 5 stars, since the add-on now does exactly what I was looking for in the extension.

However, when I looked closely at what was retrieved by Korpus (when I searched the word "name"), I found stuff being missed out. I compared what was retrieved with searching directly on Thesaurus.com.

The website produces 5 tabs of information but Korpus only presents the synonyms and antonyms from these 5 tabs.

It misses out "other adjectives related to name" and "more words related to name". Perhaps there is a technical limitation in what can be retrieved but the information omitted seems relevant.

I'm sorry if I'm being ungrateful. The add-on works much better than before. i think it is quicker too. Finally, thesaurus.com appears to use content from Roget's 21st century thesaurus, so is very up-to-date.

I'm happy to work with the dev, if he needs someone to do some testing.

I was looking for a synonym/thesaurus pop-up, rather like the right-click spellcheck in firefox.

This comes close, with a pop-up window.

I'm using firefox 46 public release with korpus 2.0

However, during testing, I failed repeatedly to find synonyms using the author's supplied thesaurus sources. I believe this is down to shortcomings in the sources used, rather than necessarily problems with the add-on.

However, another problem is the UI and the way you configure the add-on to work (i.e. it has dictionary, thesaurus and translation functionality and you control this functionality by choosing the source to search and required action). It took me a while to understand how it 'works'.

You must:

1) click on Korpus's toolbar button.

It 'should' have appeared on installation. If not, try customizing the FireFox toolbar - look through the list of available buttons. You should see a pair of curly brackets above letter "k".

Add it to the toolbar.

Unfortunately, clicking on Korpus's options in the add-on list appears to do nothing more than show you the standard details page for that specific add-on.

2) having installed/clicked Korpus's toolbar button, choose the source to search (e.g. pick Merriam-Webster from the list)

3) then type into the little search bar below, what search category you want (thesaurus, synonyms, dictionary, translation, etc - note some sources only offer certain categories e.g. English-Spanish dictionary, thesaurus, etc).

4) Then you choose the actual word to check (from the main browser window). I just double-clicked to highlight the word, then right-clicked and chose "search selection" from the context menu. You hopefully then will get a mini pop-up window with returned content.

Unfortunately, my test word was "bilingual" and had very limited success. None of the thesaurus sources I tried (below) could find this test word. I cross-checked using the provided results link - the words were absent from the search source. They did find some other words though:

- the ARTFL project - roget's thesaurus (result = "something went wrong"; tests with other words didn't work either)

- merriam webster (result = "the word you entered is not in the thesaurus"; tests using other words worked though nicely - got a dictionary definition of the word, along with alternatives)

- chambers thesaurus (result = couldn't find bilingual but did find "thesaurus" and worked nicely - information was clearly presented too. Succinct and tidy)

- oxford dictionary (result = no word found then "404 page not found" on clicking link; worked with another word though nicely and produced a lot of information).

As others have said, Korpus has great promise. The translation option could be really useful. I really like the pop-up too. It's pretty quick to find and return content. The foundation of a great extension is there.

For my purposes though, the add-on failed due to the search sources used.

I tested another add-on ("word query" by "dbyrne") which uses "thesaurus.com". This has proven more reliable in returning content. It also offers dictionary and translation options. The big issue (for me) with "word query" is it opens in a new tab. This is disruptive to workflow. It also doesn't pick up words highlighted in editors (e.g. testing a word that I'm typing in this review), whereas korpus does.

If Korpus used thesaurus.com and configuring was more user friendly, it would be really nice.

wonderfull job Betygsatt 2 utav 5 stjärnor

It really help to grasp the main meaning of a sentence or vocabulary. As there is no support section i say some word about developement here maybe developer see that. Settings lack some user friendly tools and i think if these feature be added it can be more handy and man can wait more time to fix other bugs. those features are: setting for looking up word or phrases by double clicking or pressing shortcut keys. also if it was possible to see to selectd mixed dictionary result in the same window it would be much more better. Thanks for your adds on.

Denna recension är för en tidigare version av tillägget (2.0). 

Just click on the "?", this is the Korpus configuration section: select a word/phrase + your shortcut. Adding mixed dictionary results is not really my purpose right now ( each dictionary has its own rendering) if you are looking dictionaries/thesaurus in english, I suggest you to use memidex instead.
Thx for your suggestions


One Feature Alone Has Won Me Over — Permanently Betygsatt 5 utav 5 stjärnor

Ver. 2.0 — 2 Apr 2016

I haven't ever explored the many features of Korpus Lexical. I find it indispensible because of the one feature I first discovered: the text-to-speech component.

In fact, I didn't even know what plug-in or extension was providing the context-menu item "Speak Selection"... I thought it was the Google TTS extension I added long ago, but that gets in the way with a pop-up bubble, and the voice is hideous. Korpus provides a very, very advanced, professional, pleasant voice to read what I highlight on a browser page. It has one annoying bug in pronunciation (or else I've misconfigured something somewhere else), which I'll discuss with the developer.

I uninstalled it, thinking it was a scholarly citation facility, but I was wrong. When I found the TTS function gone, later, having forgotten just what I'd uninstalled, I had to find the cause. Now I know. And I'm keeping it.

Excellent work! I can't wait to explore other features.

With 1.9.8, I was receiving error messages when choosing "Speak Selection". This is no longer a problem. But where is the exceptionally good TTS voice that it used to use? It's now using something that sounds like Microsoft Anna. Did the extension always use my own default voice, or one of its own? It sure didn't sound like one of mine (Neospeech)!

And please, where can I find full documentation of the lexicographical features? They're certainly not self-evident.

AND ONE BIG REQUEST: A hot-key (e.g. "Spea&k Selection", displaying with the 'k' underlined) would make it possible to very quickly automate the activation of this feature. A configurable shortcut/hotkey (e.g. F11 or Ctrl-Alt-S, or whatever the user chooses) would be best of all!

Many thanks.

Thanks for your remarks and suggestions:

a)TTS with Korpus use voices from functionality from google translate (or ispeech, reverso). e.g if you choose google translate then german it will translate auto -> german or "TTS" with a german voice.

b) shortcuts: just click on "?" , a new window will open: this is the Korpus configuration section.


More work needed Betygsatt 2 utav 5 stjärnor

Korpus is still rough around the edges but has potential. Oh and I need to know how to report problems as there appears to be no "support section" to log issues to. Happy to increase the rating when improved! I had problems with the alignment of the search dialog in ff43.0.3 Win10 it would get clipped in maximised screen mode! Could do with some improved documentation as it took me a while to find the "adequate" key!

Sounds good if it worked Betygsatt 3 utav 5 stjärnor

3 Stars for potential.
FF 40 (on Win7) it shows as a blank pop-up.
The 'console' shows in the wrong place.
The rest of thew interface seems to work, but blank is not useful...

extremely useful and promising Betygsatt 5 utav 5 stjärnor

Hi, I really like this add on, works great, just one question how do i change the language, i tried to use almaany dictionary on arabic word but its translating into french, i need english, thanks for the help
i can see a typing box "language pair", i tried typing #english and -- eng but i can't change the "-- fr #french" on top

thanks for the quick update. it works now, it is searching as I type so when i typed "en" "english" came up and after clicking that the language pair was successfully changed.
my firefox is 42.0, ive gone through and tried most of the dictionaries, most of them are working (especially ones with "dictionary" in the name), some give a 'blank' box - im guessing its because the word definition isn't available or that dictionary doesn't translate the selected language, so for anyone experiencing blank box try different words/languages and change the language pair to make it work

I really appreciate this add-on but today I've installed the new firefox 29 and it works at the begining but now it look like this : http://oi62.tinypic.com/w7zk82.jpg
And It's not usable anymore...
Please make an update. Thanks in advance

Because of the new firefox skin, width allocated to the widget/toolbar seems too small
I already fixed it in V1.6.3 regardless of the plateform used,
Should be released by firefox soon.
Meanwhile you can download it here;

Nice but should be in the context menu Betygsatt 4 utav 5 stjärnor

Very nice addon and very nice concept. But I had to uninstall it. I'll reinstall it for sure, yes, yes, yes... but ONLY when "F9" (or any other Fx) will be replaced (or completed) by a command in the context menu. Not before.

Done, should be released by firefox by the end of the week
