Bug Description
In Mozilla we've detected a spike of crashes in the Ubuntu-packaged version of Firefox 69.0.x. All the crashes are happening in the WebRTC code and specifically libc's FD_SET, FD_CLR and FD_ISSET range-checking safety is causing an abort. Is it possible that Firefox is being built with a FD_SETSIZE value that's different from what's used in libc?

This crash is happening in the Ubuntu-packaged version of Firefox. It seems to affect 64-bit users only. I'll file a bug on Ubuntu's tracker and link it here.
