3D Warehouse Downloads, Version pull down menu does not appear

I’m using Mozilla browser. I am not given a choice of versions upon downloading. I use Version 8.0.4811. Pro. When I accept or save as, the model is rejected as I receive error message that I need Version 15.3.331 in order to download. Help? I need a small pine tree and a White Plain Dodge Ram Truck ( No big tires ) in order to finish an Architect’s rendering. Any suggestions appreciated. Joe

did you try right clicking for the download options?
