For instance, blog posts with multiple pages of comments would show (on the main page) that the number of replies has increased from 80 to 95, but actually viewing the comments page will only show 80 comments just like it was several hours ago. Refreshing doesn't show me the current version. Its like it's retrieving an old memory of the page instead of the current one. But if I've cleared cache and cookies for that site, then it shouldn't be able to do that, and should instead show me the current page. Either way, when you refresh it should show the current version of the page regardless of any data it's saved somewhere. So either way, something's not working right. When it happens, I have tried refreshing the page multiple times. Also, re-entering the URL, or re-clicking the link from another page to load that page. But it still persists in showing me an old version of the page. A few inconsistent times I managed to get it to show me a newer version, but then on a refresh it would show me the old previous version again. It's happening in multiple websites, which makes it unlikely to be site specific. Especially since it doesn't happen on every page on those sites, just a few that I visit often. This problem has only been happening since updating to firefox 4 which makes me think it's a glitch with browser.
