Pop-ups are one of the most bothersome parts of the online world.

So, the fact that Mozilla's Firefox browser comes pre-packed with a pop-up blocker — no extensions necessary — is a great perk.

But, there are also times when you actually want to allow a pop-up to see the light of day.

For instance, when watching sports online, videos are often presented on a smaller, pop-out window — a window that may get blocked by Firefox's overzealous pop-up blocker.

Fortunately, you can selectively let pop-ups sneak by on certain websites without disabling Firefox's otherwise advantageous pop-up blocking tool.

Here's how to allow pop-ups on Firefox for certain websites, using your Mac or PC.

How to allow pop-ups on Firefox

1. Open a new Firefox window or new tab by clicking the "+" sign next to an open tab or tabs on your Mac or PC.

2. Click the gear icon in the top-right corner of the tab, which will direct you to your Preferences.

3. Once you're in Preferences, click the three vertical lines in the top-left and select "Privacy & Security" from the options.

4. Scroll to the "Permissions" section, near the bottom of the page.

5. By default, the "Block pop-up windows" box will be checked. Leave the box checked, but click "Exceptions…" You can also uncheck this box to turn off the pop-up blocker altogether.

6. Type in the address of the website that you want to allow pop-ups for, then click "Allow."

7. Finally, click "Save Changes."

The website should immediately appear under "Website" with the status "Allow" in Firefox's "Allowed Websites - Pop-ups" window.

If pop-ups from an exempted website become bothersome and you'd like to change your mind, you can always remove the website in the same Preferences page.
