Menu path: Setup > Sessions > Browser > Browser Global > Advanced

In this area, you can change various settings as well as add or change user-defined configuration parameters.

You can change the following settings:

  • Use old searchbar: If this option is enabled, the logo of the search engine currently set will be shown in the search window. If this option is disabled, the search engine currently set will not be shown in the search window and search suggestions will be shown in the drop-down menu.
  • Always use the cursor keys to navigate within pages: If this option is enabled, caret browsing will be enabled when the browser is launched. If caret browsing is enabled, you can navigate with the keyboard in websites without using the mouse. With the insertion mark, you can copy text to the clipboard.

    You can enable or disable caret browsing at any time by pressing [F7]. To prevent caret browsing being disabled, you will also need to enable the Setup > Sessions > Browser > Browser Sessions > [session name] > Settings > Hotkeys > Disable Hotkeys for Starting Caret Browsing option.
  • Find As You Type: If this option is enabled, search suggestions which match the characters typed will be shown while you type.
  • Warn me when websites try to redirect or reload the page: If this option is enabled, a message window will be shown as soon as a website tries to get the browser to load another website or reload the current website.
  • Check my spelling as I type
    Possible values:
    • Off: Your spelling will not be checked while you type.
    • On for multi-line controls: Your spelling will be checked if you are typing in text fields with multiple lines.
    • On for multi- and single-line controls: Your spelling will be checked if you are typing in text fields with one line or multiple lines.
  • Use autoscrolling: If this option is enabled, you can launch automatic page scrolling by clicking on the middle mouse button to place a scroll symbol in the text and then positioning the mouse pointer above or below the anchor.
  • Use smooth scrolling: If this option is enabled, you can browse through a page using the [Page Up/Down] keys smoothly as with scrolling. If the option is disabled, the display will jump immediately when you press the [Page Up/Down] keys.
  • Disable GStreamer in Browser: If this option is enabled, GStreamer will not be used to play back videos. This may be a good idea if you experience problems when playing back videos.

    We recommend that you disable this option if there is no multimedia codec pack installed on your thin client and you wish to view videos on HTML5 websites.
  • Disable OpenGL acceleration: If this option is enabled, hardware acceleration with OpenGL will not be used. This may be a good idea if you experience problems with OpenGL applications,

To add a user-defined configuration parameter, proceed as follows:

Changes to the advanced Firefox browser settings can impair its stability, security and speed. IGEL Support is not responsible for problems caused by changing the browser configuration, even if the browser configuration was changed in the IGEL setup.

The configuration parameters can also be changed in the browser via about:config. To do this, the Browser Sessions > [Session Name] > Window Settings > Hide Browser Configuration Page option must be disabled.

  1. In the Custom preferences area, click on .
  2. Using the Active option, specify whether the configuration parameter is to be active.
  3. Specify the Mode of the configuration parameter.
    Possible values:
    • pref: You can change the value in the browser via about:config. When the browser restarts, this change will be lost and the value set here will be used.
    • defaultPref: You can change the value in the browser via about:config. When the browser restarts, this change will remain.
    • lockPref: You cannot change the value in the browser via about:config.
    • clearPref: You cannot change the value in the browser via about:config and the value will not be shown via about:config.
  4. Under Custom preference, give the name of the configuration parameter. Example: ui.textSelectBackground
  5. Specify the Type of the configuration parameter.
    Possible values:
    • String: The value is a string of characters.
    • Integer: The value is a whole number.
    • Boolean: The value is a Boolean value, i.e. true or false.
  6. Specify the Value of the configuration parameter. The possible entries depend on the Type selected.
  7. Click on Ok.
    The configuration parameter will take effect the next time that the browser is launched.

    You will find information regarding the configuration parameters in Firefox in the MozillaZine Knowledge Base under Firefox About:config entries.
