Why is Firefox writing so much data all the time?

I am running Windows 7 x64 and Firefox 8. In my Task Manager I display the I/O Write Bytes of all processes. I have found that Firefox is ALWAYS the Process with the largest amount of write bytes after it has been running an hour or so even though there are dozens of other processes there. The only Web page is Google and all of my plugins are disabled.

Firefox may be updating the phishing protection database or do maintenance with other files like places.sqlite. It should stop at some point if that has been done.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem.

I did as you suggested and there is no difference. After running for about 20 minutes I checked my Task Manager and Firefox is the highest in I/O Write Bytes as usual. Any other ideas?

Have you ever checked your own machine to see what it is doing?

I guess you haven't. I suggest that you try it and watch your Task Manager to see how much data the Firefox process is writing for yourself.

I'm not on Windows, so can't check for that.

Try to check with Process Monitor to which file(s) Firefox is writing
