Over time this can make it difficult to print things normally, and you might be wondering how to get Firefox to use its original, default settings.

Our tutorial below will show you a way to quickly go back to the default print settings in the Mozilla Firefox Web browser.

Summary – How to Revert to Default Firefox Print Settings

  2. Click inside the address bar, type about:config, then press Enter.
  3. Click I’ll be careful, I promise.
  4. Click inside the search field, type print_printer, and press Enter.
  5. Right-click on print_printer and choose Reset.

Our guide continues below with additional information on how to reset Firefox print settings to their defaults, including pictures of these steps.

Windows 10 updates have been happening a lot more frequently of late (whether they are intentional or not) and one issue that I have been noticing is an increase in printer problems.

These are most commonly seen as general issues where the printer needs to be completely reinstalled, or a driver needs to be updated, but they can also extend into specific programs.

One problem I encountered involved Firefox. It was possible to print pages from the browser, but I was seeing errors if I tried to open Print Preview or change some print settings.

Fortunately, it is possible to reset Firefox’s printer settings by following the guide below.
