I opened up Firefox with Sandboxie and this message popped up. What does it mean???

What do I have to do to fix this

 

It tries to copy a file that is too big for the sandbox. You must set a higher value like 60MB in the file migration settings of your sandbox. I had the same problem.

 

How do I do that

 

Sandboxie Control > right click on applicable sandbox > Sandbox Settings> File Migration. In that window is a field for you to change migration file size. I think the default value is approximately 32 mb.

 

Thanks Doodler that fixed it.

urlclassifier3.sqlite - contains the database of phishing sites for protection from web forgery.

Here I turn off "Tell me if if the site I'm visiting is a suspected forgery..." under FF's options - Security tab and delete urlclassifier3.sqlite.

Not saying anyone should do the same but FF seems better here without it and what do I care what site I go to when I'm in the sandbox.
Google sqlite probs
