Set the default page scaling ratio of Firefox

Firefox does not have the same default display ratio as other browsers. Therefore, if the screen resolution is high, the default display page of Firefox is small, which makes reading inconvenient. In this case, we usually manually adjust the page to the appropriate proportion to browse the page. For example, we often use "Ctrl +" to enlarge the page and "Ctrl-" to narrow down the page. However, when a new page is opened, it is still the default page size, which makes browsing inconvenient.To change the default page size, you need to expand the Firefox browser as follows:

Start the Firefox browser, find "tool"-"add-ons" in the toolbar, and click "extensions" on the pop-up page )", in this topic, find "Default full zoom level 4.9" (Note: 4.9 is the version number) and add this component. After adding the component, click "option" of the component )",In the dialog box that appears, enter the default page size you want to set in the upper-right corner and press close to exit.
