Thanks for the info CT, but for those of us using private browsing and vpns, this isssue still persists. It can only seemingly be cleared if browsing openly and non-securely. Is there a solution for us browsing privately ? All data is cleared and caches report 0 as expected, but still getting 502 when logging out. It isn't a big issue, as cookies work as should in private browsing because of manual cookie whitelists, and sites still operate normally per purge-cacheing. It probably is more likely firefox screwing up as they always do every update
