Auto Tab Opener

Auto Tab Opener is a simple Firefox addon that allows you to open multiple URLs at once and to store them locally.

Get the Add-on


Use Auto Tab Opener for example if you have several social media pages open all the time and don't want to open them manually every time you restart Firefox or your computer. After the restart you only have to click "open" because Auto Tab Opener saves all your URLs locally right after you enter them.
