I keep getting this popup that says "Urgent Firefox Update" and that I need to download a file firefox-patch.js from https://ohhucwimdu.org . The full website address is: https://ohhucwimdu.org/1472885999843/10219ba5e75aa1cfb-dfc186fe1319e2.html I haven't downloaded the file, I'm afraid it's a virus. Have you heard of this? If this is legit, please tell me, and I'll download the file, if it isn't, tell me how to get Firefox to quit crashing and popping this up. I've tried to post a screen capture of the page, but, it takes forever to upload.
