Sandboxie Support

Sandboxie 5.20 932 bit)
Firefox 55.0.3 (32 bit)
AVG Internet Security Version 17.6.3029
Malwarebytes 3.2.2

Firefox has suddenly stopped working in sandboxie I get this error message:
"SBIE2303 Could not hook CoGetObject (1)
SBIE2224 Sandboxed program has crashed: firefox.exe [DefaultBox]"

I have uninstalled and reinstalled both Firefox and sandboxie but the problems still remains.
Any help appreciated.
Thanks.

Jimmy888, can you please report here if Firefox loads as normal after the fix - assuming it works. For me the initial first page load time went from reasonably quick to 45seconds.

I've gone back to v16.151.8013 and am hoping turning off auto-updates stops the otherwise forced v17 update. PITA as I'll have to update the virus database manually.

Thanks.
