# Customizing &brandFullName;

In this section:

- Extensions

## Toolbars

This will tell you how to rearrange, hide, add, and remove toolbars in &brandShortName;. For those who are unfamiliar with the terminology, a toolbar is the (usually gray) box above the area that the web site is displayed.

- Menu Bar: This is the toolbar that contains the browser menus (File, Edit, Help, etc.).
- Navigation Bar: This is the toolbar that contains the Location Bar and the buttons used to navigate web sites.
- Bookmarks Toolbar: This is the toolbar that contains your Bookmarks Toolbar Folder bookmarks.

There are two basic methods of customizing the toolbars in &brandShortName;:

- Rearranging Toolbar Items
- Hiding, Adding, and Removing Toolbars

### Rearranging Toolbar Items

To rearrange the items (icons, buttons, text boxes, etc.) on your toolbar, right-clickpress &ctrlKey; and click on any part of the toolbar that is not a text box and select Customize.... This will bring up the toolbar customization dialog.

Drag and drop any items you want to and from the toolbars (excluding the menu items). You can also rearrange icons already on the toolbars by dragging and dropping them wherever you wish. When the toolbars and items are arranged the way you want them, click Done.

#### Special Toolbar Items

There are a few special items that are available to you when customizing the toolbar. They are as follows:

- Separators: These allow you to separate items on the toolbars with a small vertical line.
- Spacers: These allow you to separate items on the toolbars with a fixed-size space, usually around 20 pixels on most themes.
- Flexible spacers: Spacers allow you to separate items on the toolbars with a space. These spacers automatically resize to fill all of the empty space on the toolbar. These are good for positioning items on the right of a toolbar.

### Hiding, Adding, and Removing Toolbars

You can hide the Navigation Toolbar and the Bookmarks Toolbar if you do not wish to keep them on your screen. You cannot hide the Menu Bar because you cannot move the menu items (File, Edit, Help, etc.) to a different toolbar, and they must stay on the screen at all times.

To show or hide a toolbar, select View > Toolbars and click the name of the toolbar you want to show or hide.

To add a custom toolbar, select View > Toolbars > Customize. Click on Add New Toolbar (in the bottom of the dialog). This will give you a dialog to enter a name. If you enter a name and click OK, your new toolbar appears. Now you can drag and drop items to it. To remove a custom toolbar, drag and drop all the items from it, and click Done. You can also hide a custom toolbar as described in the previous paragraph.

## Themes

Themes are small files that are installed in &brandShortName; that change the look and feel of &brandShortName;. Themes are not allowed to modify the actions or functionality of &brandShortName;, only the look.

### Getting and Installing Themes

You can download and install many themes from Mozilla Update. Internet searches will find many other themes as well.

Usually when you click on a link to install a theme, &brandShortName; displays a dialog asking you for permission to install the theme. You can choose to allow the download and installation or to cancel the process.

### Uninstalling Themes

Should you ever wish to remove a theme from &brandShortName;, select Tools > Themes to open the Theme Manager.

In the Theme Manager, select the theme you wish to remove, and click the Uninstall button. You may need to close and then reopen &brandShortName; for all changes to take effect.

### Switching Themes

To switch between your installed themes, select Tools > Themes to open the Theme Manager.

In the Theme Manager, select the theme of your choice, and click the Use Theme button. It is recommended that you close and then reopen &brandShortName; so that the theme can be applied correctly.

### Updating Themes

Whenever you would like to check for a newer version of a theme that you have installed, select Tools > Themes to open the Theme Manager.

In the Theme Manager, &brandShortName; displays Update Now buttons for themes with available updates. Click the respective button for the theme you would like to update.

By default, &brandShortName; will periodically check and notify you when a new version for one of your installed themes is available. You can change this behavior in the Update tab of the Advanced panel of &pref.pluralCaps;. You can check for updates manually by clicking the Find Updates button.

## Extensions

Extensions are small add-ons to &brandShortName; that change existing browser functionality or add new functionality.

### Getting and Installing Extensions

Installing an extension involves a very similar process to installing themes. Extensions can be found at Mozilla Update.

There should be an install link for each extension on that extension's page. As long as JavaScript is not disabled in your browser, clicking this link will install the extension for you.

### Uninstalling Extensions

Should you ever wish to remove an extension from &brandShortName;, select Tools > Extensions to open the Extension Manager.

In the Extension Manager, select the extension you wish to remove, and click the Uninstall button. You may need to close and then reopen &brandShortName; for all changes to take effect.

### Updating Extensions

Whenever you would like to check for a newer version of an extension that you have installed, select Tools > Extensions to open the Extension Manager.

In the Extension Manager, &brandShortName; displays Update Now buttons for extensions with available updates. Click the respective button for the extension you would like to update.

By default, &brandShortName; will periodically check and notify you when a new version for one of your installed extensions is available. You can change this behavior in the Update tab of the Advanced panel of &pref.pluralCaps;. You can check for updates manually by clicking the Find Updates button.
