Well, I used to have this problem with SUSE and now Gentoo, so I guess it doesnt matter the distro.

Currently I use firefox 1.5.0.7, and I have this weird problem just like the old 1.5.0.5 one. I have a blog on google blogspot, and everytime I write a new entry and update my blog, the page wont display my new entry. This happens not just to my blog but with others too. Sometimes I dont know that they have updated their blogs until I try deleting the cookies for those sites. I have a dual boot on my computer and it's clear: When I reboot into windows, I can see the new entries, but can't when I come back to linux.

Have any of you ever encoutered the same problem? If so, please explain what that is and what I can do to fix that.

Thank you a lot.

Try putting an ? sign at the end of the url and see if that refreshes the page with the updates. Or try setting your cache to 0 in size to test. I don't think this would be a cookie issue, more like a cache issue.
