Hi!
I made some crashes by hands (crashfirefox.exe) in Windows 7 and in Unix

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:

Best regards, Alexey
It may be one of your extensions. Please try safe mode [1] and see if
you can reproduce the issue with your extensions disabled. If the
problem is gone then the issue is at least partly due to an extension.
You can find the problematic extension by visiting about:addons and
selectively disabling each one and restarting Firefox. A binary search
will help cut down the number of steps, but either way it won't take too
long.
Then please file a bug [2] with the information you have provided here
already as well as the contents of about:support and
about:telemetry#chrome-hangs-tab as well as the results of your search
for the possibly offending extension(s).
Firefox 55 and 56 are no longer supported. You may want to consider
upgrading to Firefox 57 if your extensions are supported. "Helping You
Find Compatible Extensions" [3] may be helpful in upgrading or finding
replacements for your extensions so that you can upgrade to Firefox 57.
