When I have Firefox running, Windows is freezing occasionally. Sometimes it is freezing every few minutes; sometimes a couple of times per hour. I find errors in the Windows event log from the ESENT service which correlate to the freezing events (see attached image). The freezing events seem to occur more often if I have more Firefox tabs open. I have tried running Firefox with add-ons disabled and have uninstalled and then reinstalled Firefox and the in both cases the freezing events still occur. The freezing events do not occur if I use MSIE or Chrome, but I would prefer to use Firefox. I have checked Device Manager for errors - there are none. The S.M.A.R.T. utility reports all OK for my C drive. I am looking for advice on how to resolve this problem. Thank you!
