A recent update to Firefox browser seems to have changed how caching works for websites. I've noticed it mainly with Reddit and their 'random' feature. I can only go to one random sub-reddit and then from that point forward it will only go to that same sub-reddit when I hit the Random link. For instance if I hit random and it takes me to say www.reddit.com/r/Ohio/ then from that point on I only get the Ohio sub-reddit when clicking the Random link. If I clear my cache and reopen Firefox I again get one click on Random and then any further clicks take me to the first, random sub-reddit. This is not replicated in Microsoft Edge or with Firefox in private windows. I have disabled all of addons to see if one of them was causing this behaviour but it made no change.
