When I tried downloading ASUS firmware for a router with Firefox it rapid fire opened 50+ tabs (more if I hadn't closed things down) before I could close down Firefox. Windows Explorer worked fine. I prefer to use Firefox, but need to go back to Explorer it seems. I don't know what the opening tabs were because they were opening so fast that they were moving across the page before i could see what a loaded tab was. Thoughts on how to fix Firefox or how to restore Explorer? Thanks.
