Disable Images in Firefox to Speed Up Page Loading




Disabling images can help you to load web pages faster. It is definitely helpful for those who have slow connections. If you’re interested, there are a number of ways that you can choose from to block all images completely or images that come from certain websites only: via Page Info, About:config or using add-ons to block images in just a press of a button.

DISABLE ALL IMAGES

Block images via about:config

Firefox used to have this “Load Images Automatically” feature in its Options—uncheck it and the images would be prevented from loading completely—but then it was hidden deep inside the about:config.

  1. Type about:config in the URL bar. Then, hit Enter to ignore the warning message that says ‘This might void your warranty’.
  2. Type permissions.default.image in the Search bar and then double-click on it to modify its value.
  3. Change the value to 2 to completely disable all images or 3 to show images only from the current websites and not from or hosted by third-party websites. To restore the default setting change it back to 1.

Disable all images in a click of button using add-ons

All of the following add-ons have been tested on Firefox 36.0.1

Don’t want to go to the about:config everytime you want to block/unblock images? You can use any of the following add-ons:

  1. Image Block 2.1
  2. Setting Sanity 0.8.2

===> Image Block
Once installed and Firefox is restarted, it adds a button on the browser’s navigation toolbar. To disable/enable images, just click on the button before you open any web page.

What you might not like from this add-on is that its toolbar button cannot be moved.

===> Setting Sanity
Setting Sanity is the add-on that brings back the missing options in Firefox: Enable Javascript and Load Images Automatically. It also provides button for these two options but they need to be added to the navigation bar (or add-on bar) manually via the Customize dialog:

  1. Install the add-on and restart Firefox. Then, hit Firefox menu button on the right and click [Customize]. Or, right-click on any blank spot in the navigation or title bar and click “Customize” to open the Customize dialog.
  2. Find the button “Load images automatically” in the dialog window.

    Move the button to navigation toolbar

  3. Drag and drop the button to the navigation toolbar (or add-on bar)
  4. Exit the Customize dialog.

Note that the icon appearance changes only a little bit when you click on it to enable/disable images. It is barely noticeable unless you look at it closely.

DISABLE ONLY IMAGES IN LINKS OPENED FROM THE PARENT TAB

“Tab Permissions” (13.01.01.01) adds 5 toolbar buttons and tab context menu for toggling tabs’ permissions: Image, JavaScript, Redirect, Plug-in, Frame. You can easily change these permissions for each tab.

In additional, “Permissions” button can toggle all permissions at once. New tab’s default permissions can be change from buttons “…(New Tab)” or add-on option. If “Inheritance” is enabled, new child tab opened by “Open Link in New Tab” (or middle-click) inherits permissions from the parent tab.

First, the toolbar buttons need to be moved to the toolbar manually via the Customization dialog.

Second, unlike the previously mentioned add-ons above, Tab Permissions provides more options in disabling images:

  1. Disable images only in the current tab (the page is automatically reloaded).
  2. Disable images for all new tabs.
  3. Disable images only for the links that you open from the current (parent) tab under the Inheritance mode.
  4. Disable images via toolbar button or tab’s right-click menu.
