Pop-up blockers are programs that prevent pop-up banners from appearing. Most browsers
offer the pop-up blocker function. Pop-up blockers can functionally work differently. There are those that close the window before the pop-up banner appears and others that block the program command for the pop-up.
In addition, there areprograms that detect the blocking of pop-up windows and switch another online advertising format instead of the pop-up banner.
Since the pop-up blockers decrease the advertising contacts, there are software that convert the pop-up format to other file formats.
