What Block Up Popper is and why you might want to disable it
Block Up Popper is a browser extension that stops pop-up windows from appearing while you browse. It works by blocking code that websites use to open new windows — both the annoying advertisement pop-ups and the legitimate ones you sometimes need, like login windows or document viewers.
You might want to disable it if a website you trust isn't working properly, or if you need pop-ups to function for a specific task. Disabling it is temporary and reversible — you can turn it back on anytime, or remove it entirely if you no longer need it.
The steps differ slightly depending on whether you use Chrome, Firefox, Edge, or Safari, so find your browser below and follow those instructions.
Key Takeaways
- Block Up Popper blocks all pop-ups by default, which sometimes breaks websites that need them to work.
- You can disable it for just one website without turning it off everywhere, which is usually the fastest fix.
- Disabling the extension takes under one minute and does not delete any of your settings.
- If you no longer use Block Up Popper, you can uninstall it completely from your browser's extension menu.
Disable Block Up Popper for one website in Chrome
If only one website is having trouble, disable Block Up Popper just for that site. Open the website that isn't working, then look at the top right of your browser window for the extension icon — it usually looks like a small shield or the Block Up Popper logo.
Click the icon, then look for an option that says "Don't run on this site" or "Disable on this domain". Click it. The website will reload, and pop-ups will now work on that page. Block Up Popper stays active everywhere else.
If you do not see that option, click the three-dot menu icon next to the extension icon, then select "Manage extension". On the next page, find the toggle next to "Allow on all sites" and turn it off. Then go back to the website and refresh the page.
Disable Block Up Popper for one website in Firefox
Open the website that needs pop-ups to work. Click the three horizontal lines (menu icon) in the top right corner of Firefox, then select "Add-ons and themes".
Click "Extensions" on the left side. Find Block Up Popper in the list and click it. On the Block Up Popper page, look for "Permissions" or "Site permissions" and click "Manage". Add the website to the list of sites where Block Up Popper is disabled.
If you do not see a permissions section, click the three-dot menu next to Block Up Popper and select "Manage extension". Then look for a toggle that says "Allow on all sites" and turn it off. Go back to your website and refresh the page.
Disable Block Up Popper for one website in Edge
Open the website that is not working properly. Click the three-dot menu in the top right corner of Edge, then select "Extensions".
Find Block Up Popper in the list and click it. Look for a toggle labeled "Allow on all sites" or "Allow on this site" and turn it off. If you see a button that says "Manage extension", click that instead and toggle off "Allow on all sites".
Refresh the website. Pop-ups should now work on that page, while Block Up Popper continues blocking them everywhere else.
Turn off Block Up Popper temporarily across all sites
If you need pop-ups to work on multiple websites at once, you can disable Block Up Popper entirely for a while. In Chrome, Firefox, or Edge, click the extension icon in the top right corner of your browser. Look for a toggle or button that says "Turn off" or "Disable".
Block Up Popper will stop blocking pop-ups on every website until you turn it back on. This is useful if you are working on something that requires pop-ups for a few hours. Once you are done, click the extension icon again and toggle it back on.
In Safari, open the Safari menu at the top left, select "Settings", then click "Extensions". Find Block Up Popper and uncheck the box next to it. To turn it back on, check the box again.
Uninstall Block Up Popper if you no longer need it
If you have decided you do not want Block Up Popper anymore, you can remove it completely. In Chrome, click the three-dot menu in the top right, select "More tools", then "Extensions". Find Block Up Popper and click the trash icon.
In Firefox, click the menu icon (three lines), select "Add-ons and themes", find Block Up Popper, click the three-dot menu next to it, and select "Remove". In Edge, click the three-dot menu, select "Extensions", find Block Up Popper, click the three-dot menu next to it, and select "Remove".
In Safari, open Settings, click Extensions, find Block Up Popper, and click "Uninstall". Your browser will no longer block any pop-ups once the extension is removed.
What to do if Block Up Popper is not showing in your extensions menu
Sometimes Block Up Popper appears as a small icon in your toolbar instead of in the main extensions list. Look at the top right corner of your browser for a small icon that might look like a shield, a hand, or the Block Up Popper logo. Click it to see your options.
If you still cannot find it, the extension may not be installed. Go to your browser's extension store (Chrome Web Store, Firefox Add-ons, Microsoft Edge Add-ons, or Safari Extensions) and search for Block Up Popper to see if it is listed there. If it shows an "Install" button, it is not currently active on your browser.
Frequently Asked Questions
Will disabling Block Up Popper affect my other extensions?
No. Disabling or uninstalling Block Up Popper does not change any other extensions you have installed. Each extension works independently, so turning off Block Up Popper will not affect your password manager, ad blocker, or any other tools you use.
Can I disable Block Up Popper for just one tab?
Not directly. You can disable it for the entire website, or turn it off across your whole browser. If you need a temporary fix for just one tab, the fastest option is to disable Block Up Popper entirely, do what you need to do, then turn it back on.
What happens to my settings if I disable Block Up Popper?
Your settings are saved. If you disable Block Up Popper and then turn it back on later, all your previous settings and blocked-site list will still be there. Uninstalling it completely will remove those settings, but disabling it preserves them.
Why is a website still not working after I disabled Block Up Popper?
Another extension might be blocking pop-ups, or the website itself might have a problem. Try disabling your other extensions one at a time to see if one of them is the cause. If the website still does not work, the issue is likely not related to pop-up blocking.
Can I set Block Up Popper to allow pop-ups only from certain websites?
Yes. In most browsers, you can click the Block Up Popper icon, look for "Manage extension" or "Settings", and add specific websites to an allowlist. This way, Block Up Popper will block pop-ups everywhere except the sites you choose.
