youtube, firefox sync not staying signed in
i have youtube set as one of my home pages and up until the other day whenever i restarted the firefox browser the site would start with me signed in so that i may view my subscribed channels and videos. it would actually give me a count of how much new content was available. now i have to sign in EVERY time and the google 2 step authentication doesnt work so i sign in with username and password, then get a message from google that doesnt work when i click "yes" i then have to request a text message and the code will work and sign me in. as i prepared to submit my question to the community i noticed that firefox browser and sync is also not staying signed in.
