The way you clear everything means that Firefox will clear everything. To have security concerns is wise. But clearing everything is not necessary. Turn off the options for cookies, site preferences, offline website data. Restart Firefox, then check if this works.

Hi Fred, Many thanks for you support.

I have tested your suggested and narrowed it down to leave only 'site preferences' unchecked.

Works perfect.

Thanks again for helping me out.

O forgot 1 thing...

Where is the logic of saving the 'saved passwords' when all options are checked while clearing the history but not you 'exceptions on passwords'?

Some users want to save, some want to clean out everything. The programs should have added a warning about conflicts. Hello,

I am glad to hear that your problem has been resolved. If you haven't already, please select the answer that solves the problem. This will help other users with similar problems find the solution more easily.

Thank you for contacting Mozilla Support.

Clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, passwords, and other website specific data.
