STL download popup issue

i’m trying to export my sketchup project to a STL file on my computer, but since today i cannot. When i click on the download STL option, i don’t see anymore a popup asking me where i want to save the STL file. Nothing is appearing as if the download option doesn’t work anymore.
Strange, 2 days ago i worked perfectly…

Look in the Downloads folder. That’s where .stl files automatically go on my machine.
