Some months ago my Opera (Windows 7 32bit) became unusable.
Before every website I wanted to contact I would have to accept a series of prompts to approve each particular site on the route to the one I wanted. This is still current - hence this access to your forum via Firefox.
My 'old' Opera had superb bookmarking, unlike Firefox! However it does look as if that issue has been fixed in Opera with the bookmarks in a sidebar instead of full screen.
So, please tell me how I can get rid of the 'Security Issue' prompts,
