These are almost always problems caused by memory shortage, as modern
firefoxes are eating away all your RAM and more (I've seen instances
of 26 GB!), see about:memory . You can lower RAM usage by modifying
in about:config
dom.ipc.processCount.webIsolated (workers per domain, maybe 1 or 2)
and dom.workers.maxPerDomain (<=10), and switch off caches:
browser.cache.memory.enable	false	
browser.cache.offline.enable	false

I got down to a few GB resident memory, see top (and then type M).
