Tried it on two images, failed on both (it didn't even attempt to extract any text). Uninstalled.

Nice idea, but its OCR doesn't work well with tiny images with tiny texts. It didn't see or misread a lot of texts. :(

If Google Translate is expensive, then why not use a different service? There's DeepL, Yandex Translate and probably many more. Google isn't even the best machine traslator. It would certainly increase the useability. The pictures I try to extract text from often have just half of a sentence, so I have to open 2 google tabs to read one sentence and it loads quite long every time a new tab is opened.

The "Copy to Clipboard" button doesn't work for me.

Every new recapture deltes the text in the textbox instead of just adding to it, so I could scann the whole sentence before going to google, instead of opening google twice.

It would be great if the capture window would be re-sizeable as it takes up my whole screen when open.

The Copyfish window also becomes invisible if I change the background color of a website with a userstyle (Stylus) to black (bc in-built darm modes are still not a thing for some reason).

Has been broken for close to a month. Besides that, there were some major flaws in the design - the addon would not display untranslated text properly, instead displaying a loading symbol for a google translate page that would never load (because apparently you need to be a paying user to get simple google translate functionality).

All in all this add on has been a good choice to have, but the newest update has several downsides.

~ I have also found repeated instances of my quick select languages not working or even being reset to the default of none. (I think what happens is whenever I try to change a copyfish setting, it resets all previously altered settings back to the default).
~ When the quick select buttons ARE there, it doesn't allow me to switch between them while it is translating, and so with the removal of the translation feature, it just keeps trying to translate forever. (It seems that I can switch languages while it's still doing the OCR, but when it starts "translating", the buttons all go grey).
These are obvious and newly introduced problems that I feel negatively impact my experience with this add on.

Edit: Unfortunately, uninstalling and re-installing copyfish did not fix any of the issues I have been experiencing, though I understand and sympathize with your provided rational about why you removed the translate feature.

If the text is on a colored background, the extension has a hard time reading it. Also it's very inaccurate when trying to guess the characters for a language that doesn't use Roman letters.

Doesn't work at all on Firefox 57.0b14.

I too have the issue with the addon not working. It says: "Unable to capture screen. Please try again when the page has loaded". Nightly 57
