People who are using USB Data Cards to browse the Internet while on travel or at business, would always be in a worry about their next broadband access bill, because most of these cards come on a download based packages and very less number of service providers would offer with a completely unlimited package.

The best way to increase your internet browsing speed would be by Blocking the Images loading on your browser. Many a times while you are reading different blogs you would find that there are different images which are also loaded in the background which take up a lot of broadband and also slow down the web pages loading. While you are on a slow internet connection its recommended to block all the un-necessary material which is downloaded through your browser which can include Background Audio Files, Images and Videos. You can do this stuff directly using your browser itself.

This is a browser option but if you want another option which can implement the same job through a Firefox Add-on called Image Block 3.5. Image Block Add-on displays a button which would allow you to block/allow loading of images on websites. This would mean that the website if accessed through data cards, wifi internet, internet via bluetooth or slow connections like GSM/GPRS/EDGE dial-up would still loading in a good speed.

IMPORTANT: To use this addon on some systems you need do follow these steps after installation. Go to View-> Toolbars -> Customise, from the dialog box drag the Image Block button onto the Navigation toolbar. Now you can use it to toggle image blocking.
