I really appreciate your wish to help.

No problem.

Amongst many search results for the symptom, I found this.

I don't know anything about the site and how trustworthy it is but the suggestions seem ok and it has a systematic approach which you could try.

"sudo apt install firefox" no problem

Sorry, I don't know what you are trying to do here.
It's not 100% clear from your reply - is chrome the only application that crashes the system ?

Yes Chrome is the only application that crashes the system
