Despite its usefulness in increasing performance of a browser in slow internet connection, Opera Turbo has one main disadvantage. Sometimes, cookies are not enabled even if browser setting has turn cookies on. So, user can not login to many sites that need cookies to access them. Checking email, login to certain web, etc. are impossible without turning on cookies.
The only one solution I know is close and open Opera window repeatedly until cookies is on. Cookies are on when user is able to log in to certain sites like Google, Yahoo, Facebook, etc. To avoid typing ID and password repeatedly, do not log out before you close Opera window.
When we are ‘lucky’ and able to log in, avoid loging out before we close Opera browser, for example keep loging in to Facebook before we close Opera browser and shut down the PC. Later, when we use the PC again and open Opera Turbo, please type Facebook url. If we are automatically signing in, that means cookies are on. If not, please close browser, open, and then type Facebook’s url again until we can sign in without typing ID and password. This method is so simple, perhaps you do not need to read this to figure it out.
