hi, this crash is coming from a third-party module (pwrshx32.dll) on your system hooking into firefox and causing it to crash. there are no results for this filename on the internet so my best guess is that it's something malicious and i'd recommend running a scan with various security tools like the [https://www.malwarebytes.org/antimalware/ free version of malwarebytes], [https://toolslib.net/downloads/viewdownload/1-adwcleaner/ adwcleaner] & [https://www.eset.com/online-scanner/ eset online one-time scanner]. alternatively you could also try searching for this file on your device and manually deleting it...
