How To Set Default Zoom in Firefox

Dear Computer Lady,

I recently started using Firefox and have been able to navigate through most of the features. One problem I’m having is when I magnify a page and open a new one, the magnification on the new page keeps resetting to 100%. If I have been on the page before, it remembers the setting and automatically adjusts.

Is there a way to keep the setting I want without having to keep magnifying every new page?

Thank you so much for all of the help over the years.


Dear John,

It appears that the “Feature” of being able to set and remember the zoom on a specific web page came with the loss of the ability to set a universal zoom for all pages.

Firefox does, however have an extension called, “Zoom Page” that will allow you to set a default magnification for all new pages.

First, you need to install the add-on, then you can adjust the settings as desired.

To get started, open Firefox, and go to:
an use the search box to search for, “Zoom Page”.

When you find it, click on the green, “Add to Firefox” button and follow the prompts to install the add-on. You will need to restart Firefox as part of the install process.

Once installed, you can adjust the settings by going to the add-ons Manager (click on the “menu” icon in the upper-right and click on “Add-ons” in the menu.)

Click on “Extensions” in the left menu, then click on the “Options” button for Zoom Page.

In the options window, click the “Zoom Levels” tab and adjust the section for the default zoom level.

Click the “OK” button to save your changes and close the dialog box and you should be all set.
