It's a great extension. I think it will be more useful if it 1) can look up two dictionary, such as look up Dictionary and Thesaurus. 2) have a navigation when a word's look up result have many sections. Thanks !
Need improvement, still to extend for better
Excellent extension, but it needs improved.
The best Merriam Webster Dictionary Extension. Thank you.
Please update the option where the tab opens immediately on the text selected. It doesn't work! But I love this extension; it's the best of its kind.
Best of the kind
Love it إضافة رائعة
An excellent extension !
Thank you for your extension. Is it possible to add a audio button in the pop window? or the audio can be played automatically? it would help to save a lot of time.
It should be more improved. 1) Synonyms should be included it's highly needed. 2) The search word window size should be made more better like the one in Microsoft Edge. 3) Voice option icon is so big and it's kinda little irritating it must be made better too. BTW, I really love this dictionary
