Re: How can I fully disable pop-up blocker? Disabling it in settings will allow only first 200 pop-ups.
You can check and change the value of the pref dom.popup_maximum on the about:config page.
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.
Use the Filter bar at to top of the about:config page to locate a preference more easily.
Preferences that have been modified show as bold(user set).
Preferences can be reset to the default or changed via the right-click context menu.
