It's a Lenovo M10 tablet and opening a Gmail link gets me a tiny window I can't enlarge.
When I follow a link from Gmail to an article I want to read, Firefox opens a new browser window in the upper left corner of the screen. I have chosen "full screen" which then goes to full screen and immediately back to the tiny window. I have changed the default to Chrome, uninstalled and reinstalled Firefox, and changed multiple settings with no success. Now I'm looking for ideas. Thanks much for any light you can shed on this issue. Joe
