autoscroll

Type: boolean

disablehistory Obsolete since Gecko 2.0

Type: boolean

Note: Applies to: Thunderbird and SeaMonkey

If false, an arrow button will appear on the end of the textbox which will open a dropdown menu of all available results. The default value is true, hiding the dropdown button. This attribute only works correctly in SeaMonkey 1.x; for Thunderbird and SeaMonkey 2.0 you should also set the enablehistory attribute; as of Gecko 2.0 this attribute is completely superseded by it.

disablesecurity

Type: boolean

Set this attribute to true to disable the security UI for this browser. Omit this attribute off to enable it.

homepage

Type: URL

This attribute allows you to set a homepage for the browser element. It does not have any correlation with the user's browser homepage; instead it is a convenient property to hold a home page. You can switch to this home page using the goHome method.

showcaret

Type: boolean

Whether or not to cause a typing caret to be visible in the content area. Default is false.

src

Type: URI

The URI of the content to appear in the element.

type

Type: one of the values below

The type of browser, which can be used to set the access of the document loaded inside the browser. If this is not set, the loaded document has the same access as the window containing the browser . More precisely: The documented loaded into a chrome window is always of chrome type. Subdocuments of chrome documents are of chrome type unless the container element (one of iframe, browser or editor) has one of the special type attribute values (the common ones are content, content-targetable and content-primary) indicating that the subdocument is of content type. This boundary has a number of special effects such has making window.top == window and preventing documents from inheriting the principal of the parent document. The type attribute on all frames in content documents is ignored; subdocuments of content documents are always content documents.

Warning: The type attribute must be set before the element is inserted into the document.

content

A browser for content. The content that is loaded inside the browser is not allowed to access the chrome above it.

content-primary

The primary browser for content. The content that is loaded inside the browser is not allowed to access the chrome above it. For instance, in a web browser, this would be the element that displays the web page. The window for the primary content can be retrieved more conveniently using window.content.

content-targetable

One browser among many for content. The content that is loaded inside the browser is not allowed to access the chrome above it. This is the preferred value for any browser element in an application that will use multiple browsers of equal privileges and is unselected at the moment.

chrome

(default behaviour): A browser, intended to be used for loading privileged content using a chrome:// URI. Don't use for content from web, as this may cause serious security problems!
