![]() They ran the entire scenario with reversed roles, at which point Alice knew that Bob’s card was lower. So finally Bob knew that Alice’s card was higher, even though he was never told what Alice’s card was. Because a full deck of cards has four copies of each face value, they limited themselves to drawing from a single suit (spades): They started out by examining their deck of cards and decided that they might as well use a virtual deck of cards, for example this deck from the Wolfram Function Repository. It was not immediately clear how to do this, or if this was even possible, but they both began to discuss this problem and put the actual card game aside for a moment. They began to wonder if perhaps there was a way for one of them to prove to the other that they indeed were holding the higher card. ![]() They argued back and forth about this, but quickly realized neither one wanted to show the other their card, and as a result, they could not start their card game. Alice was quite certain she had the highest card, but Bob was equally certain he did. With that in mind, it came as no surprise that after they each pulled a card from the deck, they did not want to divulge to each other what card they were holding. Bob works as a security specialist for a major bank, and Alice is a programmer who develops cryptographic libraries. One reason for this is that they both have jobs in cryptography. They share very few private details about their lives. Now, there is one thing you need to know about Alice and Bob. Because they are using only one suit, there can be no ties. ![]() Then, the person with the highest card value wins. To figure out who gets to go first at the start of the game, they take one suit (spades) from a full deck, and each draws a card. Import the saved passwords and bookmarks from the steps above.While catching up with my old friends Alice and Bob on Zoom a few days ago, I became intrigued by their recent card game hobby-and how they used the Wolfram Language to settle an argument. Then delete your profile and create a new one. After you're satisfied the PC is safe to use, if Refresh does not resolve the issue, then go to the Firefox menu item Bookmarks | Show All Bookmarks and Backup (export) your bookmarks. Scan your PC, and browsers, in particular, for malware. This could be due to malware, a broken profile, a duplicated profile or other causes. Of great concern is that you've lost the ability to save or view passwords. See Mozilla for more information on Password Manager. If there is a backup of these files somewhere, perhaps you can restore them (after saving the current files to another location. If you override your AV warning and use it, you might still wish to delete it afterwards, to avoid others trying it.įinally, your passwords are stored in the ke圓.db and logins.json files in your profile. Note that this is a useful forensic tool, but is considered a PUP (probably undesired program) by many anti-malware suites because of potential misuse by miscreants. Nirsoft's PasswordFox can bypass Firefox and recover user names and passwords from your profile. If that works, I'd suggest encrypting the list, and keeping it elsewhere than on the PC. Password Exporter might be able to recover them, and, even better, export them. Refresh Firefox to remove any extension that might be causing an issue. Start Firefox in Safe Mode by pressing Windows R and typing ![]() Barring that, you could try the following: First, the safest way to recover passwords is from your last backup or disk image. ![]()
