This is driving me crazy....

EVERY page I go to now in FF on this bulletin board and another one, as well as other websites, re-loads all the graphics from the server instead of caching them.

E.g., when the page comes up, all the little icons that are a part of the bulletin board are all text at first , and then you can watch them become "graphical" as the graphics load from the server.

I've re-started FF in safe mode and that didn't fix it. I'm running the latest update.

It's annoying. And on those occasions when my internet connection is slower than I would wish, it really shows down my FT experience.

Is there some dumb thing I should or should be doing, or an option somewhere, or ???
