This is sort of true. Firefox uses individual language installers. Between them, the omni.ja and some other files are different totalling 80MB+ in size per language. The selector within Firefox will the appropriate language extension XPI files and install them within your profile on the fly and then set specific parameters in the prefs.js file. These are about 1MB per language.
It would be possible to create a custom installer that bundles all of this together, checks existing profile to insert the necessary XPI files and then makes the changes to the prefs.js to a certain extent. But it could mess with outliers like folks who have set custom sub languages. It would also increase the size of the installer by about 83MB. I'm going to play with it a bit.
Sometimes, the impossible can become possible, if you're awesome!
You can just create the English version and let s change the language by themself if they want to.
That's kinda complicated for a non-English speaker. They have to get to Settings and then Languages and click on Add New Languages all in a language they don't understand, which is a tall order.
