@Gabriel_Tatu yes, it is the current version of 50.1.0
However, I also just got it working. Now I’m using the 32Bit eng(british) version of Firefox
I also tried 64Bit de, 64Bit eng(british), 64Bit eng(Us) and 32Bit eng(US), but for whatever reason they didn’t work either.
For the record, I had this problem ever since updating a 32Bit de version.
