I think the problem was that many users blocked images accidentally on the right-click menu, so the feature was "buried" a little deeper. To globally turn off loading of images, you can "uncheck the box" by changing a setting in the about:config preferences editor. Here's how: (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful. (2) In the search box above the list, type or paste '''perm''' and pause while the list is filtered (3) Double-click the '''permissions.default.image''' preference and edit the value to 2, then click OK: * 1 = Load automatically * 2 = Do not load images * 3 = Load "first party" images automatically, but no others ("first party" means the image needs to be hosted on the server shown in the address bar) This should take effect on your next page load. For an easier way to adjust this setting, you can use an extension to add a toolbar button. The following extension covers numerous different types of content, but if you only want a button for images, you should be able to show just that one: https://addons.mozilla.org/firefox/addon/quickjava/ This older extension adds a button to turn images on and off on a per-tab basis, but I don't think it can override the global setting so if you use a lot of new tabs, it probably won't accomplish your objective: https://addons.mozilla.org/firefox/addon/tab-permissions/ Hope this helps.

Also, the current version of Firefox is 36.0.1 already.
