Settings for Web Content

This preferences page provides Pale Moon settings for web content, pop-ups, fonts, and languages.

Pop-ups

By default, Pale Moon blocks annoying pop-up windows on websites. Unchecking this option will disable pop-up blocking.
Some websites make legitimate use of pop-up windows. Therefore, you can allow these sites to open pop-ups anyway. To do so, click Exceptions…, enter the site name, and click Allow. To remove a website from the list, select it and then click Remove Site. To clear the list completely, click Remove All Sites.

Images

Pale Moon allows you to control whether images in web pages are loaded or not. The default setting to automatically load all images is strongly recommended, but if your specific conditions require it, you may change this setting:
  • Automatically: Automatically requests and loads all images in a web page.
  • Never: Never loads images in a web page.
  • Originating server only: Only loads images from the same server as the web page is loaded from, and doesn't load images that are hosted on a third-party server. Although this setting potentially improves your privacy, it will not work for websites that use dedicated image servers or content distribution networks.

Fonts and Colors

Default font and Size: Web pages are usually displayed in the font and size specified here (measured in pixels). However, web pages can override these choices unless you specify otherwise in the Fonts dialog. Click the Advanced… button to access the Fonts dialog and to change this and other fonts options.

Fonts Dialog

  1. From the Fonts for drop-down list, choose a language group/script. For instance, to set default fonts for the West European languages/scripts (Latin), choose Latin. For a language/script not in the list, choose Other Writing Systems.
  2. Select whether proportional text should be serif (like "Times New Roman") or sans-serif (like "Arial"). Then specify the font size you want for proportional text.
  3. Specify the font to use for Serif, Sans-serif and Monospace fonts. You can also change the size for Monospace fonts.

You can also set the minimum web page font size. This is useful to prevent sites from using overly small fonts that are barely readable.

  • Allow pages to choose their own fonts, instead of my selections above: By default, Pale Moon uses the fonts specified by the web page author. Disabling this option will force all sites to use your default fonts instead. Please note that this may severely impact the display and usability of some sites.
  • Character Encoding for Legacy Content: The character encoding selected here will be used to display pages that don't specify which encoding to use.

Colors Dialog

Text and Background: Here you can change the default text and background color to be used on web pages that haven't specified that information. Click on the color samples to select colors.
  • Use system colors Check this option to use the colors defined in your operating system settings instead of the colors specified above.

Link Colors: Here you can change the default colors for Web links. Click on the color samples to select colors.

  • Underline links: By default, links are underlined on web pages. Uncheck this option to disable this. Note that many sites specify their own styling rules and this option has no effect on those sites.
  • Version 26 and before:
    If you are using a High Contrast (accessibility) operating system theme, colors specified by the page will always be overridden.
    Allow pages to choose their own colors, instead of my selections above: Select this option (default) to allow pages to use the colors specified by the page author.
  • Version 27 and later:
    Override the colors specified by the page with my selections above:
    • Always: Select this option to force all sites to use your default colors.
    • Only with High Contrast themes: This option will make Pale Moon use the colors specified by the web page author, except when you are using a High Contrast (accessibility) theme.
    • Never: Select this option to make Pale Moon always use the colors specified by the web page author.

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 button. Remove a language by selecting it in the list of active languages and clicking the AddRemove 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 of your listed languages.

JavaScript

Enable WebAssembly (WASM): Checking this box enables the use of so-called WebAssembly (WASM) content. WASM is a bytecode format version of JavaScript that is often used for transpiled programs and is a way for websites to deliver code that has been pre-compiled for use in the browser. For more details on WASM see e.g. Wikipedia's article on WASM

Video

These settings control several aspects of video playback on web pages.
  • Enable Media Source Extensions (MSE): This enables the use of Media Source Extensions, a streaming media delivery method used for video on a number of websites. This is enabled by default.
  • Enable MSE for MP4 video: This enables the use of MSE for media in MP4/h.264 video formats. This is enabled by default.
  • Enable MSE for WebM video: This enables the use of MSE for media in the WebM video format.
