Since few days I am experiencing this issue. I was logged in to Twitter with my primary twitter account @debiprasad on Firefox and I had selected to remember that log in. I decided to use Twitter with my primary account on Chrome and use another Twitter account on Firefox. So, I signed out, and signed in with my other username. I selected the option to remember this login (with the new account). I don’t remember exactly, but I think there was no problem for first few days. One day, when I opened Twitter on Firefox, I saw I am automatically logged in as @debiprasad. I tried to sign out, so that I can sign in with my other account. But after page loads, I found that I am again logged in as @debiprasad. Again I tried to sign out and finally it showed me home page (when no one is signed in). Then I able to sign in with my other username, with “remember me” selected.
It worked for the day. But on the next day, when I booted my computer and opened Twitter, I found that I am automatically signed in with @debiprasad. And the same story continues. It does not sign me out on my first attempt. Then it signs me out on the second attempt. Sometimes, it shows some error on the sign out url (different error at different time). When I reload that page, it shows me a new “Sign out” button to confirm that I am trying to sign out. After clicking on that it shows me Twitter home page, with no one signed in. From that day, it happens everyday, when I open Firefox for the first time.
I don’t understand what’s going on. I don’t have a clue to know whether it’s the problem of Twitter or Firefox. I am trying to find this out. And then I will update this post.
