Hi, in Firefox there is no one-size-fits-all zoom. Instead, the zoom level you set is remembered for each site you visit.

More - Font size and zoom - increase the size of web pages.

If your question is resolved by this or another answer, please take a minute to let us know. Thank you.

Try to set layout.css.devPixelsPerPx to 1.0 (default is -1) on the about:config page. If necessary adjust its value in 0.1 or 0.05 steps (1.1 or 0.9) until icons or text looks right.

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

You can look at the Default FullZoom Level or NoSquint extension to set a default font size and page zoom on web pages.

That is not true in my experience. Firefox always initially loads pages with the universal default zoom level -- even the pages which it "saves" when I close the browser, then reloads when I run Firefox again.

If what you say is true, then where does Firefox save the zoom level for each and every page? That could be an extremely large file(!!).

The zoom level is saved per domain as part of the Site Preferences in content-prefs.sqlite.
