How to change language default in Firebase console web?

After having struggled with this for some time, and also after following Google's solution to clear cookies, cache, and everything else (https://firebase.google.com/support/faq/), DOCS still showed in a different language for me (only docs, not console or anything else). What I found out is that there's a drop down menu at the bottom of the docs page (right next to Terms and Privacy) where the wrong language would be set to, so I just changed that to English and it seems to be working for now without resetting.

For me, even if I removed all languages except english and signed out and in again, console was still in Spanish, so just adding &hl=en to url helped https://console.firebase.google.com/?pli=1&hl=en

To change the default language you can go to this page:

https://myaccount.google.com/language

and change your default language for the Google Related Apps and services.

You need to change your google account settings from French to English.

If you don't want to change it just add URL parameter as ?hl=en https://console.firebase.google.com/?hl=en
