Firefox will not save my form data after I close and then open it again. It will remember the form data for the current open session. Here are my settings:

Under Privbacy:
Checked: Remember what I enter in forms and the search bar
Unchecked: Always clear my private data when I close Firefox
Checked: Ask me before clearing private data

I have "Tab Mix Plus" installed and it's session manager turned on. The settings are:

Checked: Enable Session Manager
Checked: Enable Crash Recovery
Under Restore: All options checked
Under Preserved: All options checked

I am also using the remember password function:
Checked: Remember passwords for sites
Checked: Use a master password

I checked that the formhistory.dat file is writable by Firefox by:
1. close firefox
2. deleted the file
3. open firefox and go to a form and type something.
4. close firefox again
5. the formhisotry.dat file is created.

But when I open Firefox again, what I typed before (under step 4) is not there.

I am using:
OS: Vista Busniese (that could be the problem. :) ) I found that the profile is under:
This is then copied to:
Is this correct?

Firefox version: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-GB; rv: Gecko/20080311 Firefox/

This problem started a while back, long time before the current upgrade. I think it started when I enabled Firefox to remember passwords. But I am not too sure.

I am just hoping I have overlooked something and it's easy to fix. :)

Does it work if you start Firefox in -safe-mode?

If starting in Safe-mode works then disable your extensions (Tools > Add-ons > Extensions or use the option in the Safe-mode window) and re-enable them one by one until you find which one is causing it.
Close and restart Firefox after each change.

For more, see: Standard_Diagnostic (MozillaZine KB)
(e.g. try a new profile to test if it is caused by your current profile)
Transferring data to a new profile (MozillaZine KB)

Thanks dickvl!!! The safe-mode worked. It turned out to be an add-on call UnPlug. I check the settings, but it didn't say anything about form data. But I don't seem to need it, so I have uninstalled it.

Thanks again. All the links you provided are very helpful for diagnostic and backup. :)

Correction, it was not UnPlug, It's Kodak EasyShare Gallery Companion. But again, the setting doesn't refer to form data. But I can live without it.
