Filter Forge Forum IS available in other languages in Microsoft edge?

Hello, I have discovered something weird and that I do not understand. I have been using Firefox, Opera and Chrome browser, and now I am using Microsoft Edge and surprisingly it seems that ALL the whole Filter Forge website is translated into Spanish, but of course this is not available in other browsers.

As of course not everyone using FF knows and speaks well english, I thought that this discovery could help you get the FF website (and seems to work for all other webs) in your own native language

So I want to ask to other FF users that may have non-english native language if it may it also work in your own language according to the configuration of your country in Windows and if you can test it yourself and confirm if this may be true

I am using Windows 10 with Microsoft Edge Version 109.0.1518.61

I did not do anything to translate it and it is something automatic and is not a configuration made by myself in the Edge browser.

Here is a screenshot showing the FF Forum translated to Spanish

Thanks
