I'm using a 3G dongle for internet at the moment, and will be for the next few months. I'm using Opera Turbo to save on precious bandwidth (uses roughly a quarter of my usual browser). However, Opera does not seem to like my laptop and is constantly crashing. Furthermore, Chrome is my main browser with all my bookmarks, settings and various other things so I'd prefer to use that if possible.
Is there a service that does similar to Opera Turbo and compress images and such before sending them on that I can use in Chrome?
