The basic version should be English. But it is possible you downloaded from a local sever, and local language

 

Go Firefox org and get the English version.

 

Second options

 

Download from same server you use, but change the language, there is and option to download in several language.

 

In the download page look at bottom You should see -- > Download in another language <--

This gives English version. I use it (Win10 is in Finnish) because translations are hard when troubleshooting issues.
