I set up Firefox Sync on a computer with a large monitor (a TV actuall) and I had to increase the DPI in the Gnome monitor settings in order for text to be readable on the large monitor. Now, using Firefox Sync on a laptop with a much smaller monitor, it appears the DPI settings have been synced for Gmail. Gmail somehow stores this information and Firefox has synced it. Is there a way to avoid this? Perhaps I should ask Google instead?
