Why does VSCode external links don't open and make firefox crashing - firefox

Question

OS version: Ubuntu 17.10 x64
VSCode version:1.17.2 x64
When I click on a link in VSCode which refer to an internet URL (ex:on welcome page at startup>Help>Introductory videos) it opens 2 "Mozilla Crash Reporter" windows with "Firefox had a problem and crash"
I tried to disable all Add-ons in Firefox and VSCode, but the issue is still there.
I tried to re-install VSCode
I didn't find a way to ask VSCode to use Chrome instead of Firefox...
here is the Modzilla firefox report content:

Answer 1

Follow this workaround and it should be fixed:
Remove and purge the current installation using sudo apt-get remove code --purge (or in case of using snap, snap remove code).
Download and install the deb package from https://code.visualstudio.com/download
sudo dpkg -i <vscodefile>.deb

Answer 2

I resolved this issue by setting Chrome as "default browser" on my Ubuntu and then re-install VSCode
