How can I remove users from being able to clear history?

I need to know how to lock preferences for the parameters of the story. I don't want users to be able to change the settings of the story and I already tried the local method - settings.js and mozill.cfg. But the settings don't not gray in the menu options once I put them and that's what I want. I know that my file is playing because I have other parameters that are shown in italics in the subject: config that I blocked. I'm using the wrong settings of the to do it eventually? Or is there another method that I need to use. I already followed all the 't' on this page: http://kb.mozillazine.org/Locking_preferences

Here is my test mozilla.cfg file I created:

//

lockPref ("app.update.auto", false);
lockPref ("app.update.enabled", false);
lockPref ("app.update.service.enabled", false);
lockPref ("toolkit.telemetry.prompted", true);
lockPref ("browser.rights.override", true);
lockPref ("browser.startup.homepage_override.mstone", "ignore");
lockPref ("browser.shell.checkDefaultBrowser", false);
lockPref ("privacy.item.downloads", false);
lockPref ("privacy.item.cache", false);
lockPref ("privacy.item.formdata", false);
lockPref ("privacy.item.history", false);
lockPref ("privacy.item.offlineApps", false);
lockPref ("privacy.item.passwords", false);
lockPref ("privacy.item.sessions", false);
lockPref ("privacy.item.siteprefs", false);
lockPref ("privacy.item.cookies", true);
lockPref ("browser.preferences.privacy.selectedTabIndex", 1);
lockPref ("browser.preferences.privacy.selectedTabIndex", 2);
lockPref ("browser.preferences.privacy.selectedTabIndex", 3);
lockPref ("browser.preferences.privacy.selectedTabIndex", 4);
lockPref ("browser.preferences.privacy.selectedTabIndex", 5);

Who you trying to change in the settings Option > privacy and you want to prevent others to change?

You crashes only the settings in 'Clear history of Firefox closing' and not the main parameters.

You can take a look to the topic: config page to see if it has affected prefs by activating / disabling the checkboxes.

I don't know which have effect. privacy.item * Pref.

The subject: config page shows only one for privacy.item.cookies and the source code makes clear to me also.

I don't know why you want to include items such as sessions (active connections, basic authentication) used by FTP servers and disk cache and offline cache (offlineApps) application.

People should be able to delete data in the event of problems and clear the cache and cookies must be one of them (we recommend a lot of times to clear the cache and cookies).

Clears the form data and research should also be possible unless you disable save both passwords and form/search data.

Note that only tools > Options > advanced tabs, then browser.preferences.privacy.selectedTabIndex will have no effect.

Browser.history_expire_days preferences and browser.history_expire_days_min are obsolete in the current Firefox and used only versions in versions of Firefox 3.

    How can I remove it?

    Hi gunnermac,

    You should take a look at the Knowledge Base How to set the home pagearticle. Your home page might have been changed by a particular site. Sites like MSN, Yahoo, etc. have been ask to become your homepage.

    There are the steps in this article to reset your preferences on the default home page. I would try everything first to clear all strangeness. If it works, you can try to set your homepage again to your personal preferences.

    If Yahoo has been set as the default search in the search bar, you should take a look in the Knowledge Base using the search in Firefox bararticle.

    If the address bar search has been changed, so you can take a look at Search the Web from the address bar.

    If this does not work, you should look the article How to fix preferences that will not save.

    Finally, your problem may be because you have been hit by some malware.

    Hope this helps!

  • How can I remove entries from the catalog of PSE 8 Organizer when his picture does not appear in the browser?

    I imported a group of files in the folder, and organizer gave me the pop-up "new files in track files" and imported correctly.  Then I used Windows to copy these files in the folder B, also a control folder.  Once again, organizer gave me the pop-up "new files in follow the folder" correctly, BUT showed no files imported into the browser, despite everything show, etc.  I used Windows to delete all files in the folder B, then has tried to re - import.  Organizer doesn't say ' no file imported, because they already exist in this folder.  Apparently, the files are saved in the catalog, even if they are not physically there.  How can I remove these catalog when there are no photos in the browser, I can click and say ' Delete catalog?

    Oh, ugh!

    The answer to your question of title, is that you cannot correct this situation by using the Organizer.  Without a doubt, something in your database (catalogue) is screwed up.  The database is a SQLite database, so if you know someone who is a type of database that is experienced, it can use a database query tool to clean the entries in the media_table table.  This can be more or less a complicated matter, depending on how much other data you must save - you will certainly need to work closely with him on this issue.

    The best thing to do, of course, is to create a new catalog and start from scratch.  Lose all your work with labels and albums will result, but...

    At least now you know how to get copies of your photos in the Organizer in the right way.
