Saved logins & password
Gets lost (half of them to say the least) every time Firefox updates. I checked the box that ask for saving the logins and password in the Privacy and Security section and this feature has always been active. I must have saved logins for 36 websites and email providers. Very vicious cycle and you know how frustrating this can be. Well you can help by either fixing this bug or do away the feature all together. Because next time this happens AGAIN I'll revert back to good 'ol Google chrome and never get back to using Firefox ever.
