Hi!
I made some crashes by hands (crashfirefox.exe) in Windows 7 and in Unix
through kill -ABRT
What are the symptoms? In random moments the Firefox v56.* has only-one
core CPU 100% eating. In Windows 7 (64bit) & Linux (Ubuntu 16.04 LTE
64bit)
Reports are here:

Hi Alexey,
These crashes all seem to be stuck in sqlite code querying the places
database that contains browsing history. In the Windows crash, you can
see that thread 0 is waiting on a sqlite mutex for the database, and
thread 44 is in the middle of running some sort of sqlite query, so
presumably it's holding the mutex.
These are actually all bookmark queries, and unfortunately,
main-thread, blocking bookmark queries, at that.
My best guess would also be an extension, but WebExtensions at
least should not be hitting these code paths.
