I have Explorer 11. The cookie setting has been the same for years. Why would it be a problem now? What setting, if necessary, should it be?
To check the setting, open the top right corner drop menu, then find Internet Options. On the General page, it should have a section listed as Browsing History, with an option you can check to "Delete Browsing history on exit"
If that option is still unchecked and your getting this error, try clearing out your cookies and cache completely and sing in again. Still an issue, let us know.
Using Firefox I can open pictures but the keypad is slow and jumpy I have been using Explorer but cannot open pictures. I prefer Explorer. Tried to post this on Firefox but it would not let me, it said Shockwave was busy
Not getting the same error as you with Firefox. What version are you using? I tested with 49.0.2. You can double check that with in your Advanced Settings, under update.
The error with IE opening images is one I've noticed on a couple of sites, and we have the tech team investigating a fix. As Microsoft pulls support for IE in favour of Edge, it's getting harder to keep it compatible, so I can't make any promises but we will try our best
