Firejail vs Docker sandboxing for web browsers

On windows there is a tool called Sandboxie that isolates programs in containers. I know there is firejail and docker for Linux sandboxing but I just need it for Firefox. There have been lot of code execution exploits for a lot of browsers so to prevent malware from getting in I could just sandbox the browser. If attacker want to get in from a web browser it will need at least 2 different exploits to get in. Which sandboxing solution for Linux is better Firejail or Docker which is more secure and has more features?
