Introduction
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.

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
Disable the extra menu items for the Personal Toolbar – if this is checked then the items above will not appear in folders on the Personal Toolbar.
When Groupmark folders are opened, add
The items here add items to groupmark folders as above.


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.

Duplicated Link Protection
These options determine what happens when you try to open (in a new
tab) a link that already exists in an existing tab. You can either
have it open the duplication document, or switch directly to that
document.
New Tabs
This selects what actions should open in a new tab. Currently
available options are middle-clicking on a link, a link whose
target is set to _blank, a form whose target is set to
_blank and links from external programs.
Middle mouse clicks
These define what happens when you click a link with your middle mouse
button. The link can be opened in a new tab or a new window.

International Domain Names
Enable International Domain Name support in Mozilla –
if this is checked then international characters will be allowed in
domain names
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.

New Window Redirector
Enable new window redirector for window.open() –
intercepts requests to open new window from Javascript and allows you
choose what to do with them. By default, these requests can be
allowed to open, redirected to a new tab, blocked completely or you
can be asked each time what to do.
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 javascript:window.open() to new tabs – Links that use href="javascript:window.open()" 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="javascript:window.open()" 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.

Privacy Options
MultiZilla can automatically delete various privacy items when the
browser is closed. Select the items that you want to have removed
when the browser closes in this section.
Confirmations
You can have MultiZilla ask you before deleting these items with this
option.

Tab Bar
Last tab action – this drop-down box defines what
happens when you close the last open tab. You can have a blank page
loaded, you can have a blank page loaded and the tab bar hidden or you
can have the browser closed down.
Hide tab bar for single tab – if this is checked then the tab bar will be hidden when only a single tab is open.
New Tab and Focus Order
New tabs will open at – this defines where a new tab
will appear when opened. Valid options are the start of the tab bar,
the end of the tab bar or to the left and right of the currently open
tab.
Close tab will switch focus to the: – this defines what gets focus when you close an active tab. Currently you can have focus switched to the tab at the left or the right of the current tab. In future you will also be able to have it switched to the previously selected tab or the last tab to be opened.
Middle-Mouse Clicks
A middle mouse click on the tab bar defaults to: – this
option defines what happens when you click the middle mouse button in
the tab bar. You can either open a new tab or have the last opened
tab closed. You can use the Shift key to perform the other action to
what is selected in this drop-down box.
Mouse double clicks
Open a new tab for mouse double-clicks on the tab bar –
if this is checked, then double-clicking on the tab bar opens a new
tab.

New tabs should be for/from
These checkboxes define the actions that cause links to be opened in a
new tab. If the item is checked, then it will be opened in a new tab,
rather than the default behaviour.
New tab failure handling
Newly opened tabs that failed to load should: – this
defines what happens when you open a link in a new tab and it fails to
load. You can have the new tab automatically closed, left open or you
can be asked what to do with it.
Preferred location
This lets you set the page that will open when you press Ctrl+Shift+T
(the 'preferred location'). You can enter a full URL or use the
buttons to have this set to the home page, the current page, or a file
on your computer.
Miscellaneous
Enable automatic tab selection after X milliseconds –
if this is checked then if you hover your mouse over a tab, that tab
will be selected after X milliseconds (where X is defined in the textbox).
Enable middle mouse clicks on tabs to close the tab – if this is checked then clicking on a tab with the middle mouse button will close it.
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.
Use Cmd-left/right arrows for back/forward (Mac only) – this is available on Macs only. If it is checked then pressing Cmd+left/right arrows will take you back/forward in the history instead of going to the previous/next tab.

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.
Save and restore tab history – If this is checked then the last X items in the browser history (ie the pages visited, as used in the Back/Forward buttons) are saved. X is defined in the Maximum items to keep box.

Tab Icons
Show load indicators on tabs – if this is checked than
an LED will be put on the tab to indicate the load status of the
current page (red=loading, yellow=pending, green=ready)
Favicon on tab, site icon on tab – if these
are checked then a 'favicon' will be displayed on the tab (a site icon
is a favicon that is directly loaded by the page through an HTML
<link> tag).
Close X icon on tab if this is checked then when you hover the mouse over a tab, an X icon will appear that lets you close the tab.
Tab Label
This lets you choose what label should be used for a tab. Current
choices are the page title and the page URL. For
long labels you can also choose how they should be cropped. You can
crop them from the start, from the end or in the middle. You can also
choose the maximum and minimum sizes for labels before cropping occurs.
Tab label colours – a future update of MultiZilla will let you set background and foreground colours for tabs.

Force auto-complete to remember your login/password – Some sites like on-line banks use autocomplete="off" to disable Mozilla's password prompts so this preference will change "off" into "on".
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.
<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).
