Preference Manager Help Page


MultiZilla is about giving you the freedom of configuring it the way you want, thus we had to add a large number of new preference panels, but switched to our own Preference Manager with MultiZilla v1.5.0.2 (then optional). Later versions of MultiZilla use an even better Preference Manager, which is were this page is all about.

The following page jumps are available:

Note: The documentation for our latest version of the Preference Manager (v4) can be found here.


The screenshots on this page are reduced in size and have a limited quality; they are provided as examples only and may vary from release to release. Please note that other operating systems and browser themes might also affect the layout and colors.

Main Panel
MultiZilla's main panel has no control over preference settings. It is only a place holder for some information about when MultiZilla was first introduced. Note that we used this image as splash screen for a long time, but we removed it to reduce the file size of the download. However, you can still download it, if you want.

Tab Bar Position
This defines where the tab bar should appear. This the toolbar that shows the tabs. Valid positions are the top and bottom of the browser window. By default, the tab bar appears at the top of the window.
New / Close Tab Positions
These define whether the new tab and close tab buttons should be shown. By default, neither button is shown
Use MultiZilla Preference Manager
if this is checked then middle-clicking on the QuickPrefs button will show only the MultiZilla preferences tree in the prefs window.
Use MultiZilla XPInstall Confirmation Window
if this is checked, then the Seamonkey XPInstaller will be replace with that of MultiZilla, which provides much more information than the default.
Use Stacked Windows for MultiZilla Managers
if this is checked, then the Tab-, Session-, Permission- and User Agent managers will cause all child windows to be opened on the exact position of the parent window, but stacked windows cannot be moved. The content of new stacked windows will be displayed like a curtain i.e. from top to bottom, while normal windows will (try to) display everything at once.
Note: selecting stacked windows on OS/2 might result in a crash!
Use Classic Theme Cycling
This is a Windows 95/98/ME/2000 specific preference for people that are forced to use the classic Windows theme (it selects specific CSS rules in our stylesheets to make it look right).
Hide the sidebar tabs and show View button
if this is checked then the tabs in the sidebar (Bookmarks, History, etc) will be hidden and a button called 'View' will be shown at the top of the sidebar with a drop-down menu letting you access all the panels of the sidebar. This gives you more screen space for your sidebar.

Bookmark Menu Behavior
Open new tabs for bookmarks in background – if this option is checked then when bookmarks are opened in tabs, they will be opened in the background, while the current tab retains focus.

Enable middle-click in a bookmark menu (opens a new tab) – if this is checked then middle-clicking a bookmark in the bookmarks menu, button and sidebar will open that bookmark in a new tab.

Close bookmark menu after mouse middle click – if this is checked then the bookmark menu will close automatically after you middle-click on an item. If this is unchecked then it will remain open for you to select further bookmarks. You can close the menu by clicking outside it.

When Bookmark Folders are opened, add
MultiZilla can add additional menu items to bookmark folders. This pref panel lets you choose which of these get added. The items are described below.

Open folder in tabs – open each of the items in this folder in new tabs
Open folder in windows – open each of the items in this folder in new windows Open folder in a window – open each of the items in this folder in tabs in a new window Use folder as home page – select this folder as your home page so that each item in it will be opened when you select your homepage

The Full Screen preferences (or settings) panel gives you control over...
Full Screen panel

Full Screen Mode Configuration
From here, you can control how full-screen mode works.

Enabled for first browser window only – Toolbars are normally hidden in Full Screen mode, so this preference makes it possible to display the toolbars for the first full screen browser window only, or all Full Screen windows.
Disabled for kiosk-style browser windows – The toolbars in kiosk-style windows are normally hidden by default (chromeless) and this preference makes it possible to skip kiosk-styled windows. You might want the toolbars, but you might not want them in kiosk windows.
Use F11 to enable Chrome for kiosk-style browser windows – Using F11 will try to enable chrome i.e. change kiosk-styled windows into 'normal' browser windows so that you can open/close tabs etc.

The boxes labelled Mozilla toolbars and Third party toolbars contain the available toolbars. Those toolbars with a check next to them will be visible in full-screen mode.

Display URLs with International Domain Name in Punycode – displays URL that have non-ASCII characters in them in punycode

Display warning for new and suspicious looking domain names – note: for this to work, you must have the master password enabled (although you can leave this blank). Since some IDN characters can look almost exactly the same as ASCII ones, they can be used for phishing attacks. Checking this box allows MultiZilla to create a hash for each secure site (https) that you visit, so if a site is uses a malicious URL to take you to a phishing site, you can be notified at a glance.

Automatic Update Notifications
Enable automatic update checks – should MultiZilla automatically check for updates to itself? You can check daily, weekly or monthly. You can also perform a manual check from here.

Override new window features specified by websites – a website may open a new window and specify what toolbars, menubars etc are visible. If you check this box, you can override this and always show the items that are ticked in the specify window features drop-down box.

Synchronise 'dom.disable_window_open_feature' preferences – MultiZilla uses its own preferences for window features, but this preference makes it possible to change the default prefs of Mozilla as well.

Redirect to new tabs – Links that use href="" instead of target="_blank" are sort of special for Mozilla so we need this preference. You might want to open a new tab for target="_blank" but a new window for href="" or vice versa.

Tab Popup Indicator
Display popup icon on the tab when a new window is blocked – if this is checked then an icon will be displayed on the tab when a popup window is blocked. If this is checked, you can have the icon removed automatically after a certain number of milliseconds. If this is set to 0, then the icon will not not be removed.

Enable double mouse clicks on tabs to close the tab – if this is checked then double-clicking on a tab will close it.

Use new (empty) tabs before opening a new tab – if this is checked then if you have a blank tab open and ask for a link to be opened in a new tab, it will use the existing blank tab rather than opening a new one.

Open new tabs in the background (keep current tab selected) – if this is checked then new tabs will be opened in the background while the currently selected tab retains focus.

Load diverted windows in the background (keep current tab selected) – "diverted windows" are windows that open as tabs from other applications either in the current tab, or a new tab in the current window.

Enable Ctrl+mouse clicks on tabs (copies URL to clipboard) – if this is checked then holding the Ctrl key and left-clicking on a tab copies the URL (location) of that tab to the clipboard for pasting into other applications.

Tab usage
This set of options defines what happens when you open a groupmark, bookmark folder or tab session. You can have all the items open in new tabs, in existing tabs, or you can be asked each time. You can also have all tabs not in the set just opened closed automatically by checking the box marked close the remaining tabs.

Tab sessions
MultiZilla can save the set of open tabs when you close the browser. Use the drop-down box marked Save tab sessions on exit to define how to do this: you can either overwrite the existing session, create a new session each time you close the browser or be asked each time.

Restore tab sessions on startup defines how/if the saved session should be restored when the browser is restarted. You can restore the tabs in the first window only, you can restore all the windows or you can choose to be asked each time. You can also choose to have the session manager opened on startup for maximum flexibility.

Skip 'Navigator Startup' settings from the Navigator preference panel (only available if restoring session on startup) – if this is checked then preference selected in 'Navigator Startup' in the Navigator preference panel will be overridden.

Skip confirmation for restoring a 'Single Window Tab Session' (only available if restoring session on startup) – if this is checked then MultiZilla will skip the confirmation dialog when only one window is open, but your confirmation will be asked for when more windows are opened.

Skip saving for tab sessions with only one tab (only available if saving sessions on shutdown) – if this is checked then sessions with only a single tab in a single window are not saved.

Remove 'onsubmit' from forms (needed for Yahoo) – You need to remove the onsubmit from forms on sites like Yahoo! and that's what this preference will do, it removes the onsubmit.

Auto Scroll
Enable auto-scroll (use middle mouse click to initiate) – if this is checked then clicking the middle mouse button on the page enables auto scrolling, which lets you scroll up and down the document by just moving the mouse up and down and not using the scrollbars or the mouse scroll-wheel.
Automatic page refresh
Enable automatic page refresh specified by META/HTTP refresh – if this is checked then if a page specifies an automatic refresh or redirect (either with an HTML <meta> tag or through an HTTP header) it will be allowed. If this is checked then you can fine-tune this with the drop-down box. You can select that automatic refreshing is allowed, that it is blocked or you can choose to be asked each time. You can also choose to have an automatic page refresh through a <meta> tag converted to MultiZilla's own page reload function (available by right-clicking a tab selecting Reload tab(s).
