Ever since version 50.0, Firefox consistently crashes / freezes every time I try to download a file / save-as an image. I've seen this reported by others as well. This makes Firefox very much unusable for me. Perhaps someone here will pay attention to that.
(fixed you try to I try to make it more about me ;)
He's another person reporting [0]. It happens even on safe mode, and I'm on Mac OSX without any AV installed. It started happening only a few releases ago, so not sure what has changed in the download manager. If I go back to, say, FF 45, then it's all happy.
I’m sure it’s nowhere near as simple/reproducible as you’re making it out to be. At any rate, I couldn’t reproduce it on my clean installation of Firefox 57, so there is that at the very least.
(Hint: if your post said “every time I try” instead of “every time you try,” I’m sure it would have been better received.)
