1) Open Firefox. Its icon resembles an orange fox wrapped around a blue globe.
2) Click ☰. It is in the top-right corner of the window. A drop-down menu will appear.
3) Click Options. This gear-shaped icon is in the drop-down menu. On a Mac, you will click Preferences here instead.
4) Click the Content tab. It is either on the left side of the window (Windows) or the top of the window (Mac).
5) Uncheck the “Block pop-up windows” box. This option is below the “Pop-ups” heading in the middle of the window. Doing so will disable the pop-up blocker for your Firefox browser. Alternatively, you can click Exceptions… to the right of the “Block pop-up windows” box, type in a website’s address, click Allow, and click Save Changes to allow pop-ups for a specific site, but not your entire browser.
