While I am trying to log out from a gmail account on firefox , a new tab pops out informing me about problem with the cookies options. I couldn't follow the instructions in the tab, because I couldn't find anything of the suggestion in the options menu. Then I checked everything that online mozilla support suggested and nothing seems to be wrong with the cookies, they are activated. I don't know if this is connected with this problem, but the account that I am trying to log out is not mine, it belongs to a friend that has ever logged in before through my firefox until yesterday, and since then I am stuck with her account and basicly I can't even have acces to my emails. I think that's all. Thank you!!
