Sometimes we are in the situation where alone network available is one with Poor Internet connection (hotspot-uri, Mobile networks in regions without signal etc). In such cases, Web pages It loads very hard, especially if they contain a large number of images, what makes Internet browsing very difficult. If you are in such a situation (poor internet connection) and you want to improve as much as browsing on the web pages, if you are interested only information text displayed on these and you may be missing images, in Firefox you have the option to Disable automatic loading of images.
In previous versions of of Firefox browser, the option to disable the automatic loading of images on the web pages was available in Tools > Options > Content. After the version is launched Firefox 23, that option has been moved below about:config, to prevent users from activating it by mistake.
How can we disable the automatic images in Firefox?
- taste about:config In the browser address bar and give Enter (In the warning screen, click on the button I’ll be careful, I promise!)

- then tatter permissions.default.image in the field Search
- data double-click on the displayed result (or click-right > Modify), modified the value it in 2 (the default value it is 1)

And ready. After you make this change, Automatic Firefox images will be disabled (For reactivation, change the value back to 1).
Note: If you want the images on the same site to load automatically, but you want to deactivate the load-party images, set the value 3 for the permits.default.image.

I have previously used Firefox for several years. But now I have to quit.
