After restarting Firefox or even rebooting: copyfish icon greyed out.
Remove.

edit after reply:
Fair enough - I'll try the older version.
The 1 star is there because there's no zero star: meaning it does nothing.
I must add that Copyfish does work on Chrome, but until I get the full hang of it I'll refrain from giving one or more stars there. Besides I work in FF and only revert to Chrome if everything else fails.

edit2: It turns out it was not an older version, but a newer version where you have added support. Kudos to you for doing that.
However my one star was well deserved then. For there was nothing in the version history that even hinted at previous versions not being supported. Nor is/was there a requirements part.

This add-on is amazing! Works as described. Truly amazing!

I have tested this add-on using English, Japanese and Spanish text, and its yield has been surprisingly successful. Not perfect, but good enough.
I tried it on complex and difficult to read text (from blurry or pixelated photos) and the results, although not completely accurate, were sufficiently close, and in some cases 100% perfect after a few retries.
Copyfish cannot read vertical text at all (such as Chinese or Japanese) but horizontally formatted text is generally not a problem.
There are some quirks with it and the interface can be fiddly. A few times I found myself having to reload the whole page from the browser in order to make the add-on retry the OCR work since the buttons just stopped responding, but it was never more than a small time-consuming problem.
All-in-all this add-on may very well save you a lot of time typing from an image, specially if you don't have the means or ability to type from a language that uses a different alphabet than your own, be that Latin, Cyrillic or Hiragana.

THIS ADD ON IS AMAZING
