Screen OCR Translator por Alex

This add-on uses optical character recognition (OCR) to capture text from any selected area of a web page and translate it. You can switch between the original and translated text, copy it to the clipboard, or listen to it using text-to-speech.

How to use:
Activate the add-on from the browser toolbar, context menu or keyboard shortcut. Select the screen area and click 'Run OCR'. You can also right-click any image and choose 'Translate this image'. The translation is rendered in place on the captured area (default mode), or as a panel in the bottom-right corner.

Keyboard shortcut

Press Ctrl+Shift+F to select a screen region for translation. To change the shortcut, open about:addons, click the gear button, and select Manage Extension Shortcuts.
