Intermittently, when I open www.makeuseof.com in Firefox, I see an older page (it is happening right now). Afer 2 or 3 days, it updates and I see many posts which I would miss (or go to “older posts” options and read) if I did not use Internet Explorer for browsing this site.
It happens only with Firefox and only with makeuseof site. I visit many other sites which are updated more than once daily and I get the updated page only.
A minor problem, since I can always open the site in Internet Explorer and browse. But still I am curious why this might be happening.
