Auto translate of web pages does not work with headless chrome

[sra...@gmail.com]

Environment:

Selenium (python) + chromedriver 

Chrome version : Version 81.0.4044.138 (Official Build) (64-bit)

I am using following mechanism to cause auto-translation of web pages with Thai to English.  

prefs = {

"translate_whitelists": {"th" : "en"},

"translate" : { "enabled" : "true"}

}

driver_options.add_experimental_option("prefs", prefs)

The translation works when using headed mode and page source returned by selenium has translation content.

If switch to headless mode using --headless option, the pages are not translated.

I believe the translation feature is a feature implemented in //chrome, not in //content. Since headless is based on //content and not //chrome, I think it makes sense that it is not supported.

(So this is probably by design)

Even if not, you probably need a Google API key for the translation to work (which comes built in with Chrome, but not with headless, I suppose).

Actually, I needed to run headless chrome because I am running it inside docker container.

I switched to headful chrome using Xvfg inside container and the translation works.
