Each time I open a site, the site exceeds the screen size until I manually zoom out. How do I fix this permanently?

For no apparent reason recently, when I open a website with Firefox, the site's homepage or any other visual exceeds the screen size of my monitor. It did not previously do that and I have not intentionally or knowingly changed any settings. I can click on VIEW and then ZOOM OUT twice and it fits the screen. What can I set/fix so that the initial page on the screen is properly sized like it used to be.

Thank you.

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 (current default value is -1.0) to restore the behavior of previous Firefox versions.

Use 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 the layout.css.devPixelsPerPx pref.
