Firefox সহায়তা ফোরাম

Hello, Firefox keeps signing me out of Google websites like google.com and youtube.com when I close out the browser. I recently switched from Google Chrome and was wondering if this was a Google issue or if it was Firefox. It only keeps me signed out of Google accounts, and keeps me signed in for every other website. I have the "Delete cookies and site data when Firefox is closed" box unchecked and it still keeps me logged out, and I have "cookied" unboxed in my Clear History settings as well. I'd like to have this issue fixed as soon as possible for school-related reasons.

Despite having logged into Which? via FireFox, and accepted all cookies I am asked again and again on every Which? page about cookies.

How can I stop this?

Is this Which? or FF?

Could you kindly advise? WashingtonPost.com does NOT ask to accept cookies even after I deleted all cookies, website data and cache (but in Opera it does ask for cookies), after Firefox automatically deleting cookies and website data after closing Firefox, and after cleaning cookies, website data and cache with Ccleaner — WHY? Which mechanism of Firefox is exploited by WashingtonPost.com? And what should I do? Thank you!
