I am running Firefox Nightly 63.0a1(2018-07-18), and i have a problem with the crash reporter booting itself up when firefox is closed (as in i close it myself, not as a result of a crash)

I have no idea if this is because I'm somewhere else other than home, maybe when i tried using the wifi off of a travel bus, but when I close Firefox and try to open a different program, it opens up in a white screen forcing me to switch to window view and see what's open. The app says nightly crash reporter. I did not open that, nor have I done anything that would result in it opening. I have McAfee installed on my phone, and all scans report there are no viruses. I don't exactly know how to report this to bugzilla. Help is appreciated
