Excellent Rated 5 out of 5 stars

Sometimes having shortcut or hotkeys is good. And it may collide with other shortcut or hotkeys.
This Add-On has a good solution. Contextual rightclick menu options.

Only worked on 1 of 8 dictionaries Rated 2 out of 5 stars

Only worked on "Bee Dictionary", which is better than nothing. Also it incorrectly says "Define" to use a thesaurus.

This review is for a previous version of the add-on (2.7.1-signed). 

Thank you for using the add-on

I've released a new version of the add-on that should fix the issues you were seeing earlier. You might want to try this latest version 2.8. Thanks!

Great idea but unstable here Rated 3 out of 5 stars

Great idea and useful when it works but there are issues here. The pop-up text appears and quickly disappears leaving an almost blank pop-up saying 'Definition not found'. Once this happens on a page, no more pop-ups appear at all on that same page unless I reload it. It must be a clash with another extension but who knows. I would give this 5* if it was more stable.

If you are using EPUBReader to read books and need to look up words without leaving its interface, you will need this dictionary add-on. Works great! The definition is shown at the bottom of the page and with another click, the definition is gone. Very hand for Epub readers.

Great addon! Rated 5 out of 5 stars

Would be complete with a sound / voice button to sound out the word, Some other addons do this but i like this one better. Can you add the Sound / Voice button at least for the free dictionary?

Works smooth and fast. Rated 5 out of 5 stars

It works really well, no more copy/paste and opening up a dictionairy in a second tab for me! (for english is not my native language). Amazingly fast and smooth too, especially if you consider it gathers its information from different websites. A thesaurus would be a great addition. Thanks for creating this.

Thanks for your encouragement! Do try out version 2.6, which has 3 different thesauri.
