It's so quick and easy to get a spelling or a definition. That's all I wanted and it was the only way I could find to meet those needs. I don't know if there are other ways to get there but it was what I found.

Quý lắm mới cho 5* đấy nhớ. Tiện ích làm như cớt ấy

Gracias muy bueno, se puede buscar en el Wiktionary en español (Wikcionario) poniendo en la caja de texto de las opciones, Language #1 (required): es

Doesn't support instant definition-popup showing with double-click.

Nice add-on, but I want to have an option to turn off the context menu for it. My browser toolbox is buggy and I couldn't seem to get the CSS ID for it. What is the CSS ID for the context menu of this add-on? So that I can turn it of myself, thank you!
Edit: Nevermind, found it, "#_3b70ac6e-090b-4455-b0be-ab852255cfee__context_find_meaning"

Excellent extension. Works all the time for me.Never had a problem. Switched to firefox from chrom for privacy reasons (do not like google's data collection). I was missing the pop up dictonary though .This great extention helped me out. Thank you so much for offering this. Really appreciate it.

It captures cmd-Q on Mac, which is the command to exit an application. ctrl-Q is a very common command on both Windows and Linux as well. Please change it, or at least give us the option to.

This extension is the best I found for FF57, it does everything I need and it is very convenient.

Thank you very much!

This is good! I started using this after an older Wiktionary plugin whose name I forgot stopped working when Firefox stopped supporting XUL. With that older extension, you could right-click a highlighted word and click a menu option that gave you an on-page window showing the full Wiktionary page for that word. This plugin has a few other ways to trigger looking up words - a neat optional button that appears over highlighted words, a toolbar button you can click to look up the highlighted word, or a hotkey (CTRL-Q). The page that pops up is a modified and shortened Wiktionary page. If the highlighted word is not on Wiktionary, the add-on can still often find the correct translation by looking it up in some other source.

For me, there are only two things that make this a 4/5 instead of a 5/5. First, the modified Wiktionary page that this plugin displays is missing a few things, such as translations. Second, and most importantly, the hotkey is not editable in any obvious way, and in Firefox on macOS it is set to CMD-Q, which is also the system hotkey to close programs on macOS. The extension overrides the system hotkey, which means that you can no longer quit Firefox in the most convenient way with the extension enabled. (Oh yeah, and the plugin defaults to the Vietnamese Wiktionary version, but this is very easy to change. :) )

Came here from the wiktionary extension by zen, which could point and translate words with a hotkey, which allowed translating buttons and links, that are hard or impossible to select. Hopefully this extension will add this option.
Also the information given in the popup interface in wikitionary was a lot less messy - easier to read right away.

Good, i like it. But, when i using "Reader View" mode in Firefox, Quick Dictionary isn't work. Why?

It works as well as it claims it does. I think it's the most convenient dictionary compatible with 47+

I only see the green button appear sometimes, but most times it doesn't do anything.

very good

Have tried many dictionary extensions but this is the best!
Thank for your amazing job!

Rất tốt nhưng cần phát triển "Double click" vào từ để tra ngay :)
