 Hi, 
 I also had the same SBIE2314 issue with Firefox 74. My solution has been: 
 - Right-click the Firefox icon 
 - Select Properties 
 - Go to the Compatibility tab 
 - Check the box: "Run this program as an administrator" 
 Firefox can now run inside a Sandboxie 5.33.3 sandbox. 
 However, this causes (in my PC) a little issue. If I try to open the real, unsandboxed Firefox, the UAC (User Account Control) asks me if I want to execute Firefox. I then say "Yes" and again the UAC asks me if I want to execute Firefox and on and on. The solution is to uncheck the "Run this program as an administrator" checkbox. 
 I hope this also works in your situation.

Regards, 
 Felix
