After upgrading to Win10 1809 .PNG files are shown much too dark in Firefox. Other Browsers handle the .PNG files correctly. Example: www.buienradar.nl now shows a completely wrong dark picture. I added 2 jpegs with wrong (buien1) and correct (buien2) display (as jpegs).

This can be caused by a problem with the color profile for your display monitor or color profiles embedded in images. Try to disable color management to test if it is caused by a problem with color management. You can set the gfx.color_management.mode pref to 0 on the about:config page to disable Color Management. You need to close and restart Firefox to make the change effective.

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
