Fix for Google Translator addon (broken API)
The addon stopped working because Google discontinued the google.com/async/translate endpoint it relied on, as well as the TKK token system used as fallback.
Solution: Replace the _getEmbedTranslation function in lib/common.js with a call to the stable translate.googleapis.com/translate_a/single?client=gtx API, which requires no token and returns clean JSON.
The new endpoint URL pattern:
h t t p s://translate.googleapis.com/translate_a/single?client=gtx&sl={from}&tl={to}&dt=t&dt=bd&dt=rm&dj=1&q={word}
The response is parsed via data.sentences[].trans to extract the translation, and data.src for the detected source language.
The returned object structure is kept identical to the original so the rest of the addon works without any other changes.
How to apply: Open the .xpi file with 7-Zip, navigate to lib/common.js, and replace it with the patched version.
