Firefox crashes

I'm having repeated crashes on launch. I've made sure most things are up to date and I don't have any malware that I can find, but this issue seemed to come honestly out of nowhere. I didn't install or download anything I don't trust, or make any changes to my computer.

I've uninstalled and clean-reinstalled a new copy of Firefox from Safe Mode, which seemed to work until I rebooted into regular Windows and the crashing restarted. I went back to Safe Mode to do it again, and I'm currently browsing on it from there but don't know what to expect after further reboot.

Maybe of note is that at first I also had a crash in CCleaner several times, not on launch but when I went into the Registry tab. I've reinstalled and updated that from Safe Mode as well, with again no apparent further issues while still in Safe Mode, but haven't checked it in full reboot yet.

I haven't checked IE, but thankfully had no issue with Chrome so was able to at least try to address this. Any help much appreciated!

What Security Software please ? If Comodo there seems to be a issue.

Yeah I'm running Comodo and I did indeed find a ton of Firefox files blocked. I'll keep an eye on it but things seem to be all good now, so thanks for the tip-off!
