What to do when the preferences aren't showing up in the preference manager?

A completely new preference manager was written for MultiZilla version 1.7, which is nice of course, but you might run into trouble when you keep your old profile after the update from a previous version. You basically have two options to solve this problem. The first one, the easiest one, is to ditch your profile and to use a new profile. However, you will lose all your settings so you might want to try the second option. Open the following file with your favorite text editor:

browser directory/chrome/overlayinfo/communicator/content/overlays.rdf

and replace the following URL:

chrome://communicator/content/pref/preftree.xul

with this one:

chrome://multiviews/content/preferences/multizillaPrefOverlay.xul

That should work, but feel free to join us on the newsgroup, just in case you can't get it working without further assistance.

How can I modify CTRL-N to open a [window/tab] instead of a [tab/window]?

CTRL+N opens a new window in Mozilla (or should) but certain versions of MultiZilla changed this behavior and open a new tab, instead of a new window. This behavior can be changed on MultiZilla's Tabs pref panel. Simply untick the checkbox in front of 'Ctrl+N' and it will open a new window.

Note: people that like to open a new tab, instead of a new window, should tick the checkbox.

The underlying pref is: user_pref("multizilla.newtabfor.ctrl-n", [true/false]);

How can I change MultiZilla startup behavior?

You can startup Mozilla with a blank page, home page or the last visited page. The pref settings for this can be found on Mozilla's Navigator pref panel. I guess we all know that by now but...

MultiZilla adds a new and very powerful feature called Tab Sessions. One of the options of this feature enables you to restore one or all previously open windows and tabs on startup.

Tab Sessions can be restored automatically, without your interaction, or it let you decide at startup. The latter will open a dialog window or MultiZilla's Tab Session Manager. All pref settings for this feature can be found on MultiZilla's Advanced pref panel.

Note: please keep in mind that you first need to setup and use 'Save Tab Sessions', before you can use MultiZilla's 'Restore Tab Session' successfully .

Is MultiZilla a skin or theme?

No. MultiZilla is not a skin or a theme, but we do have a theme OSXilla available for download and installation for MultiZilla.

So what is MultiZilla you ask. Well, it is a browser add-on or a so called browser extention. MultiZilla adds literally dozens of new features, menu items and preferences for all sorts of things. You can read more about all new features in the Features Section of this website.

The MultiZilla project is one the oldest projects on mozdev.org but still very active. MultiZilla also has its own optionally installable GoogleBox widget that emulates the official Google Toolbar for Microsoft's Internet Explorer.

Note: The GoogleBox widget was developed before the Googlebar project was even launched on mozdev.org simply because I wasn't aware of its planned introduction.

Notice: We are very much aware of that other shamelessly copied project but MultiZilla is still the first and only original XUL TabUI for Mozilla based browsers.

Can I use the old (yellow wrench) as the Quick Prefs Button image?

Yes you can, by adding the following lines to: /chrome/userChrome.css in your profile directory.

  •  
  • #qpmenu-tbbutton {
  • list-style-image: url("chrome://multiviews/content/images/toolbar/preferences.png") !important;
  • -moz-image-region: rect(0px, 16px, 16px, 0px) !important;
  • }

How can I open the Preference Window in MultiZilla?

MultiZilla offers you three ways to open the Preference Window. The first two are MultiZilla specific and the last one is Mozilla's own implementation.

  •  
  • Middle-click on a QPrefs button (this button can be displayed on the Navigator, Personal and MultiZilla Toolbar).
  •  
  • Left click on the QPrefs button and select menu item 'Preference Window'.
  •  
  • Menu > Edit > Preferences and select menu item 'Preference Window'.
  •  

Note: Only the first two options select the MultiZilla pref panel at start. You will have to select other pref panels manually, like you have to when using the last option.

How can I re-enable MultiZilla after I disabled it with Extension Manager?

You can re-enable MultiZilla by entering the following chrome URI into your location bar:

  • chrome://multiviews/content/reEnableMultiZilla.xul

Tip: Select the link and drag it to a bookmark menu or to your Personal Toolbar.

Can a website open new tabs in MultiZilla?

No, not really. However, a web designer can use: target="_blank" or javascript:window.open(); to open a new window in Mozilla and MultiZilla can redirect this to a new tab. Check MultiZilla's Tabs and Popup pref panels. The settings in the Permission Manager will override this behavior!

The reason why this wasn't implemented in Mozilla can be read in Mozilla bug 105409.

The underlying prefs are:

For target attributes: user_pref("multizilla.newtabfor.windowopen", true);
For javascript:  links: user_pref("multizilla.window-open.javascript-in-tab", true);

Does MultiZilla support Mozilla Firefox?

No, not yet, but we're working on it. Keep an eye on bug 2228. Don't hesitate to get in touch with us if you can help us. We also need new images for MultiZilla's Toolbar and Pref panels.

Do the Mozilla tabs come from MultiZilla code?

Yes, both Mozilla and Netscape adapted MultiZilla, but not all of it. Mozilla Firefox goes even further by adding more features priorly introduced by MultiZilla. However, Mozilla's tabbrowser widget is a plain re-write, done by David Hyatt, a former Netscape Engineer, of some of HJ's work.

How do I get MultiZilla to work with Netscape?

Install MultiZilla version 1.5.0.0 for Netscape v7.1 from the installation page or install the appropriate XPI for Netscape v7.0. We discontinued support of Netscape v6.x simply because we lost the XPI for it :(

I get a Java error message warning me that I'm running IE!

You may have UA spoofing enabled. From the MultiZilla Quick Prefs Menu, select Browser Spoofing->Restore Original User Agent. This should solve the problem.

How do I remove MultiZilla?

MultiZilla doesn't provide an automatic un-installation script, but the following steps will solve this problem:

The following steps cover how to remove MultiZilla if you installed it for multi-user access (into the Mozilla/SeaMonkey program directory). If you installed it for single-user access (into your profile), then follow the same steps but use <profile>chrome/ where it says chrome/

  • Close Mozilla (including QuickLaunch on Windows)
  • Backup your <profile>/chrome, <program>/chrome/ and <program>/components/ directories (in case something goes wrong)
  • From the chrome/ directory, remove multiviews.jar
  • From the chrome/ directory, remove chrome.rdf
  • From the chrome/ directory, remove overlays.rdf
  • From the <program>/components/ directory, remove mzContentBlocker.js and mzUpdateNotifier.js
  • From the <program>/chrome/ directory, remove the following lines from installed-chrome.txt:

    content,install,url,jar:resource:/chrome/multiviews.jar!/content/multiviews/
    skin,install,url,jar:resource:/chrome/multiviews.jar!/skin/modern/multiviews/
    skin,install,url,jar:resource:/chrome/multiviews.jar!/skin/classic/multiviews/
    locale,install,url,jar:resource:/chrome/multiviews.jar!/locale/en-US/multiviews/

    Note: this file is always found in <program>/chrome (never in <profile>/chrome)

Now restart Mozilla/SeaMonkey to recreate chrome.rdf, overlays.rdf and the XUL cache, but please note that you might have to start your browser twice to recreate a new XUL cache without MultiZilla in it, or your browser windows might look broken.

Please install a stable release in case you are having difficulty with a MultiZilla nightly and tell us about the problem/bug which enables us to help you or fix the bug for you!
