I have the resolution on my computer set correctly. When I click on Firefox, the images are too large (wrong resolution). How do I set it for the correct resolution? I have my computer set at 1650X1080.

Reset the page zoom on pages that cause problems.

  • View > Zoom > Reset (Ctrl+0 (zero); Command+0 on Mac)

You can set the layout.css.devPixelsPerPx pref on the about:config page to 1.0 or on Windows 8 to 1.25 and if necessary adjust layout.css.devPixelsPerPx starting from 1.0 in 0.1 or 0.05 steps (1.1 or 0.9) to make icons show correctly.

Use an extension to adjust the text size in the user interface and the page zoom in the browser window.

You can look at this extension to adjust the font size for the user interface.

You can look at the Default FullZoom Level or NoScript extension if web pages need to be adjusted after changing layout.css.devPixelsPerPx.

Give these a try and see if they help.

Ctrl + increases the size Ctrl - decreases the size Ctrl 0 (zero) resets to the default
