PopupButton57+ por FireWaterAirCats

Do you want to easily turn on/off all popups without having to enter any menu or configuration? Then download this addon. It adds a little toggle button to firefox that controls if popups are turned on or off.

The addon was written to use the lowest amount of disk space / cpu / ram possible, it doesn't run any code in the background, doesn't analize what you are doing and it doesn't collect any data. It doesn't even save a single bit of data to your hard drive. If you don't trust me, just have a look at the source code, it's open source.
