Screen OCR Translator by 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, or the context menu, or by pressing Ctrl+Shift+F. Select an area of the page and click "Run OCR".

To translate an image directly, right-click it and select "Translate this image".

The translation appears over the original text. Hover over a text box to view the original text and its translation, which can be copied or read aloud. Use the extension toolbar to show or hide the translation overlay.

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.
