Not sure I fully understand what you’re talking about…
You want to change the translation for “currently browsing” or you already did?
You tried also to change the translation for “author”. Per my understanding “currently brwosing” and “author” are two different cases. Also I don’t know what you already changed and where in the code. Did you manage to restore or copy the original file so that whatever you want to change is back to default?
And you want .php to be in swedish???
BTW: A .CSS definition never have translations or wording but describe how it should look like.
