How to Enable Zoom on All Website in Firefox

 To enable zoom on all websites in Firefox, you can follow these steps:

1. Open Firefox and click on the Menu button (three horizontal lines) in the top right corner of the window.

2. Select Preferences.

3. In the General tab, scroll down to the Language and Appearance section.

4. Under Zoom, use the drop-down menu for Default zoom to select a zoom level for all pages.

5. Click Close.

You can also use the keyboard shortcut Ctrl + + to zoom in and Ctrl + - to zoom out.

To zoom in on a specific part of a page, you can use the mouse wheel. Hold down the Ctrl key while you scroll the wheel to zoom in or out.

If you want to zoom in on text only, you can select the Zoom text only checkbox. This will zoom in the text, but not the images or other elements on the page.

Note that the zoom level is saved per hostname, even after you close Firefox. For example, all pages on support.mozilla.org share the same zoom level setting, but it is different from the zoom level setting of the pages on blog.mozilla.org.

If you want to reset the zoom level for all websites, you can go to the Preferences page and set the Default zoom to 100%.
