For Firefox 4 for Windows there is for slow connections a really useful image block addon
https://addons.mozilla.org/de/firefox/addon/quickimage/
Unfortunately Firefox mobile is pretty slow and the addon doesnt exist for it. Most browsers can turn off image loading in options/settings. But often this causes horrible site look. Blocking only 3rd party image sources really makes browsing on 64kB/s mobile connections alot faster, generally you dont need things like Opera Turbo Mode, its not like dsl speed, but sites load within 5-10 sec.
So is there a android browser or a way to block 3rd party images per default. Tools like adblock dont show images with distinct path (, but download all images per default?). Im not looking for something like opera mini or opera mobile turbo mode. I know these options.
I found a solution for firefox (built-in config setting). I keep the question open, as someone may find to do the same thing on dolphin HD or Opera. Than dolphin would become my standard mobile browser.
