What does the message "CRXMAGICNUMBER_INVALID" mean? It has to do with extensions. It cannot be just a character count.
Is it some kind of checksum, or does it refer to encryption, or what?
Is that message appear after modify V7 Bookmarks?
I tried to unarchive the extension installer, modify one of the files, then rearchive it. The new archive did not install, and I got that message, "CRXMAGICNUMBER_INVALID". What is CRX? What is this "magic number"?
