I use Firefox to read the news. I have it on a schedule, so it opens up a half hour before I get up, so by the time I'm at my computer, they are all loaded & waiting. Before the last update, all the tabs would reload on start-up. Now, several sites don't. I assume they are reloading from the cache, since the page is identical to the page the day before. Hitting the refresh button will solve the problem, of course, but then I have to wait for the page to reload. Not the end of the world, but a little inconvenient. Some browsers have an option to force the browser to ignore the cache, or to delete the cache when the program quits, but I've not found a way to do either one in Firefox. Any suggestions gratefully accepted. Thank you.
