Firefox 7.0.1 ignoring custom settings for 'Clear History'
I have a MacBook Pro with OS 10.6.8 and Firefox 7.0.1
Under Preferences > Privacy, I have custom settings to clear browsing history every time Firefox closes.
However, when I relaunch Firefox, the 'Restore Previous Session' is highlighted under the History menu and I can restore the previous session.
How is this happening?

On Windows, there are two places for the "clearing history" option for FF, there's a second one under "Advanced" and "Security".
Do you have that option on Mac?
No, there is no 'Security' tab under the Advanced Preferences on the Mac version.
Sorry, but I have Windows...hopefully somebody will roll out of bed and help you soon!
It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the files sessionstore.js  and sessionstore.bak in the Firefox Profile Folder.
- Help > Troubleshooting Information > Profile Directory: Open Containing Folder
If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).
There is a sessionstore.js file in the Profile Folder but no sessionstore.bak file nor any other sessionstore files.
I quit Firefox, deleted the sessionstore.js file, relaunched Firefox and went to one web site. I quit Firefox again, relaunched Firefox but 'Restore Previous Session' was still highlighted and did remember the one web site.
- Try this.
- Type in the address bar about:config.
- Accept the warning.
- In the page that appears, in the Filter box, type browser.sessionstore.restore_on_demand
- Change the boolean value to false (which is probably set to true in your case).
- Close the about:config page.
- Restart the browser

Thank you but when I type browser.sessionstore.restore_on_demand in the Filter box there is nothing there.
May be it's different in mac. Try typing just "restore" and what it brings.
There is browser.sessionstore.restore_hidden_tabs but it is set to false
If you have private browsing mode, enable it and see what happens.
No history and no 'Restore Previous Session' is maintained in Private Browsing mode.
Are any sessionstore pref user set (bold) on the about:config page to indicate that they got changed?
There are the following boolean type files under browser.sessionstore, none of which are in bold
.restore_hidden_tabs set to false
.resume_from_crash set to true
.resume_session_once set to false
There are several integer files including
.privacy_level, the integer being 0
.privacy_level_deferred, the integer being 1
Change .resume_from_crash to false and see what happens.
No difference, 'Restore Previous Session' is still there.
Then I suggest a clean reinstall of FF. Use a free program like revo uninstaller to remove the old FF. Export your bookmarks to a html file before you uninstall the old FF.
Thank you. I have AppDelete so I shall give it a try.
One question before I do; will this also delete my add-ons?
Yes, the add-ons will be deleted. Better to save your add-ons page so that you can re-install them.
I tried that but it is still the same with 'Restore Previous Session' still being there.
Thank you astrocatlady, cor-el and amkeew for trying to help. There is something amiss so I have gone into permanent Private Browsing mode.
