I am now using Firefox instead of Google Chrome for daily use, however I read in some sites that Firefox lacks in security while being better at privacy and Chrome the other way around. Is Firefox really less secure for not having a sandbox for general use? I know it uses a sandbox for Flash, DRM, etc. Am I wrong and that is the same case in Chrome or not, because I could not find that much information about it. I am already using uBlock Origin. Will "firejail" be a good sandbox for firefox for daily use?
I am sorry for any mistake in my English.
