I have Firefox Mobile 16.0.2 installed on my Asus tablet (Android ICS, 4.0).
The images are rendered with excessive JPEG compression, resulting in compression artefacts, like non-smooth gradients, blurs, etc.
I compared it to Chrome browser and Dolphin HD, where the same images show fine.
NB: I'm using my home wifi, and it is definitely not an issue of ISP compression.
Any idea why, and how I can fix that?
