Flickr fails to display all of my albums or all of my images within an album. It loads the first 25 then shows red and blue spinning balls. Flickr support narrowed the problem down to McAfee WebAdvisor. Adding Flickr as a trusted site in McAfee WebAdvisor did not solve the problem. However, disabling McAfee WebAdvisor on my Firefox browser did solve the problem.
There is something in McAfee WebAdvisor on Firefox that prevents Flickr from displaying all the images.
I have a similar problem. If I start flickr from Firefox with web advisor enabled, flickr search functions do not work. If I disable web advisor, close then re-open F'fox and start flickr, flickr search does work.
