I upgraded to Firefox 57 Beta today and Copyfish works just fine.

Works great for Chinese and English (these are the languages I use it for)

Work perfectly .
The result need some corrections but it's very useful and simple to use.
Thanks!

I have been watching video lectures and there are times I want to copy items. It has helped me a lot to convert instantly select a part of video and convert to text.

Thanks for this addon !

It's a great tool. Thanks.

Let's appreciate that someone made an addon that did not exist before. Stop complaining for a free thing. And people spend their free time to create these free services that you are able to use.

Works absolutely fantastic on all sites I tested it with. I use it mainly for Youtube subtitles, chat translation and gaming. Sometimes you have to reload the page for Copyfish to work as the sites needs to load after Copyfish has been turned on (so it seems).

I love this utility because I have dished out good money for far lesser performing OCR products. This is a great extension!
