Good. But сan you switch the transcription to the standard IPA symbols?

I find it incredibly handy to be able to just double click a word on any website and immediately be shown its definition in a simple coloured box with large type.
The only thing that *really* bothers me is if you double click on a plural word you are only told "plural form of (whatever word you double clicked)". If I'm double clicking a word, it's not because I'm confused by the presence of an 's' at the end of it, it's because I would like to see the definition of the root word. So frustrating!
Developers, please fix this!!

Please give us an option of metakey (cmd, ctrl, alt, shift) that is required to press before the popup appears. Thank you for an excellent extension!

Very useful English dictionary.

Only problem: the "more" open a page with nothing. When I select a word in the page, please pass it to the definition window. Please, add a saving option, to save my words/definition, or an annotation.

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.

Quit working.

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.

Perfect dictionary; easy to use with very fast definitions (clearly presented) and multiple sources to choose from. Thank you for making this extension available.

Exactly what I was looking for.
The only true popup dictionary I've found for Firefox.

Perfect... but it does not work for PDF's text

simply good!

yeeee

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.
