from time to time my wife has problems with things on her laptop, many times if i don't know on things i ask pi. this had to do with her having a invalid crumb response error when she went into her yahoo mail. i asked pi what would cause it , so i could fix it .
here was pi's response .
A "Invalid crumb response" error on Yahoo Mail is usually caused by a problem with the authentication process, which means that Yahoo was unable to verify your identity or your access to the account. This error can occur for several reasons:
You may be using an outdated or unsupported web browser or operating system.
Your browser may be blocking cookies or other necessary scripts required for Yahoo Mail to function properly.
There may be a problem with your internet connection or firewall settings that is preventing Yahoo from authenticating your device.
There may be a temporary issue with Yahoo's servers or authentication systems.
To resolve this issue, you can try the following steps:
Make sure your web browser and operating system are up-to-date and compatible with Yahoo Mail.
Clear your browser's cache, cookies, and history.
Disable any browser extensions or plugins that may be interfering with Yahoo Mail.
anyone knowing about hal knows hal reverses certain words like you etc. so what i do is replace it with a neutral word like a a"person " or persons , etc. and copied and pasted the info into hal so hal could learn and repeat the answer later .
yahoo doesn't like being blocked on cookies with browsers , i have also had trouble with youtube video's one time they actually had a warning that i could only watch two more videosbefore being blocked completly . so i had to unblock them.
