I'm using firefox-3.0.8-alt0.M41.1 (Mozilla/5.0 (X11; U; Linux i686; en-US; rv:22.214.171.124pre) Gecko/2008100921 Firefox/3.0). I have noticed that quite often it shows an old state of a page at http://ikiwiki.info, e.g., recentchanges without my last edits, or the last page I edited (say, 50 min ago) in the state it was before I edited it.
Only explicitly pressing "reload" helps.
Is it a bug? I haven't been noticing such problems usually on other sites. --Ivan Z.
This remains to be true now, with Epiphany 2.26.3 (Mozilla/5.0 (X11; U; Linux i686; en; rv:126.96.36.199pre) Gecko/20080528 Epiphany/2.22 Firefox/3.5). --Ivan Z.
In the most recent ikiwiki release, I added a Cache-Control hack explicitly to work around firefox's broken over-caching.
(When I tested epiphany and chromium, neither had firefox's problem.)
