could be really good. I liked how simple it was, and the UI was clean when it displayed the definition.

however, probably more than half of the words that I actually need to search a definition for, don't show any results on this extension! the majority of the time I end up having to google it, which shows a definition fine. if there was just a wider range of words in this extension, it would be good. until then, I'm going to have to uninstall.

searching algorithm is slow.

I wish this didn't pop up when I double click text in a text field, its very annoying when I'm trying to edit text... maybe an option would be nice.

I have found this add-on as useful as I have annoying. Double clicking is a common way to activate many actions, so it can be annoying to double click for one purpose and get the spelling definition too. If the activation click were changed - Triple click? Right click and choose from menu? - I would give 5 stars.

This could be a really great addon. I've only just started using it, but if I'm to continue using it, there NEEDS to be an option to disable plural definitions for words. It does not help me in the slightest to only see "Plural form of X" when clicking on a word. If I didn't know the plural version, then I definitely don't know the singular version.

5 stars otherwise.

Nice, bit there is no easy way to turn it off. This is a problem when writing emails, editing web forms or using online writing tools (like google docs): The popup can be intrusive when you are selecting text to copy, edit, move, etc.

In Google the little red dictionary is very available by simply highlighting a word and then click on the dictionary. Here I must highlight the word then do a control C next click on the dictionary and then do a control V. You should fix this.

Works better than anything else I've found for Firefox, but not as well as the Google dictionary on Chrome.

Also I'm nervous that my AVG antivirus software periodically complains about it, implying that it's collecting data on me or some such. AVG is not very specific about why it keeps asking to delete it, but it makes me occasionally look for a replacement.

Works well, but not secure. Anything you double-click gets looked up in what I assume is clear text. That would include usernames, passwords, etc.

Very good, but works badly on web pages with dark background, can not see the text at all.

Doesn't show all of the meanings.

Would be 5 stars, but it is unusable on dark/black backgrounds, which is mainly what I use it on.

Really wish I didn't have to click the tiny X to exit the definition. Why not dismiss with a click anywhere besides the definition? Otherwise perfect

works very quickly and accurately. however there are NO settings or menu options to configure the add-on so i get definition popups when i'm trying to delete a word or edit my typing and the popup very often just gets in the way. please allow a highlight only option without double clicking, or just do a special key to initiate the dictionary.

I think could be the best add on with a few tweaks. It very simplistic which is a great thing . there's been some go I d suggestions and mine are things that would make more functional and not take away from the simplistic flow.
The 1 time I want to be a lefty ;) . I'm right and mostly on a tablet or phone so when I highlight I r double click the yellow popup is under my hand. It sounds minor but enough of an inconvenience that I will need to continue my search if a future update is not added for an option for choosing the popup side.
Doesn't need to be fixed as it's not broke but I don't like the delay and inconvenience. I wish Samsung would make a feature when you hover the Pen over a word the definition would pop up as they have pictures and hyperlinks. I think developer has done great job and would love to continue using but the amount I utilize now since getting larger phone I am only the option of some costly clunky app that's way overkill for just what's done here solely with a tiny addon.
If wanting to elaborate on addon as maybe a Pro version, I would say the Ability for us to choose or enter the site used to lookup, Choice from a few colors or a pallete of popup box, Addition of a speaker icon by word to hear it sounded out.
Now the last may be too much to ask for but that's basically what I or know others utilize. Not all these games,words of the day,share the word with everyone and just so much distracting and phone memory using features.
While browsing all needed is - reading,what's that word, click, what's the meaning, how's it sound, continue reading. Perfect App!
