thanks, unfortunately those are all already a few months old so they won't tell us much about the current reasons for the crashes :-/

so based on this i will only be able to give some general troubleshooting advice in regards to crashes: Troubleshoot Firefox crashes (closing or quitting unexpectedly)

in particular i'd recommend to run a full scan of your system for malware with multiple different tools like the free version of malwarebytes, adwcleaner & kaspersky security scan.
