Advanced Options

Advanced Options

The advanced panel contains many Options that are less likely to be used by most people but are useful and sometimes critical Options for some people.

General tab

Accessibility
Always use the cursor keys to navigate within pages
When this Option is enabled, Firefox will display a movable cursor in web pages, allowing you to select text with the keyboard. You can toggle this mode by pressing F7.

Search for text when I start typing
When this Option is enabled, Firefox will find within the current web page what you type as you type it. While you are finding typed text in the page, the Find Toolbar will automatically display at the bottom of the window to show information about what you've found.

Browsing

Use autoscrolling
Autoscrolling is a useful feature which allows you to scroll the page by clicking the middle mouse button (usually the scroll wheel) and moving the mouse up or down. Some people find this annoying, so autoscrolling can be disabled with this Option.

Use smooth scrolling

Smooth scrolling can be very useful if you read a lot of long pages. Normally, when you press Page Down, the view jumps directly down one page. With smooth scrolling, it slides down smoothly, so you can see how much it scrolls. This makes it easier to resume reading from where you were before.

Check my spelling as I type

When this preference is enabled, Firefox will check your spelling and offer possible corrections as you type in web forms. Note that you may need to download a dictionary; to do so, right-click on any text field, enable spellchecking if necessary, and then use the provided Languages menu to download a dictionary.

Languages

Some web pages are offered in more than one language. Click the Choose... button to specify your preferred language or languages.

Languages Dialog

To add a language, click Select a language to add..., choose the language, and click the Add button. Remove a language by selecting it in the list of active languages and clicking the Remove button. You can also reorder languages using the Move Up and Move Down buttons to determine the most preferred one in case a page is provided in multiple languages .
