There is another option to reduce your data use, but it requires allowing Google to know everything you do. Google has data compression routines that will compress all web traffic you use in selected browsers when this feature is on. Opera from the App Store is one of these. In the Settings area, you can have it do maximal compression on data prior to it being sent to and from your device. That could help for bandwidth limited use.
Other downloadable browser apps have implemented this feature. I do not use it, when available, but you might want to.
