The Strict Pop-up Blocker allows you to quickly toggle between blocking all pop-up windows and allowing some pop-ups. If pop-ups are not your thing, this add-on for Firefox is for you.
Here is more about the add-on from the developer:
By default Firefox blocks most pop-up windows but allows some to appear.
This add-on adds a button on the toolbar to toggle between:
- the default Firefox behavior of allowing some pop-ups, and
- blocking all pop-up windows.
Pick up the Strict Pop-up Blocker at the Firefox Add-ons website.
