No, you probably want to keep cookies.sqlite because it stores all your cookies, good and bad. (Actually, Firefox should re-create a new blank one if you zap the file, so wiping it out is only temporary anyway.) To block specific sites from saving cookies, you can add them to the Exceptions list. Alternately, you can set Firefox to expire the cookies after each session. In that case, you can create an Exception for sites that you want to remember you between sessions (sites where you get tired of logging in each time). For more on how to customize your cookie settings, see: [https://support.mozilla.com/en-US/kb/Enabling%20and%20disabling%20cookies Enabling and disabling cookies | How to | Firefox Help] Does that help?

Yeah, that helps quite a lot. Million thanks.
