The inital reason to creating this addon, was so i could "CTRL+Click" on one of
my bookmark folders which contain (quite a few) bookmarks and the containing
bookmarks would open without the browser freezing or becoming unresponsive,
because i am sure my PC is a actually a potato in disguise. Since i could not
find any other addon which at the time seemed to be able to do this, i created
this addon to fill the gap.

Usage/Features

• open background tabs (for example via CTRL+Left Mouse Button)
• (optional) set black/-whitelist URLs on the preference page

Notes:

1. Can/Should i trust this addon?
   You can view the source code by either visiting the Homepage/Support Site or just saving/downloading the XPI (which is really just a ZIP Archive) and then extract it locally. The Sources in the XPI should be unofuscated and unminified (HTML,CSS and JS), so it's as easy to read as possible. Alternatives you can also use the CRX Viewer Extension by Rob W to inspect the XPI sources. If you have an questions, you can also open an issue on the support site and i'll try and answer to the best of my abilities.
   If you are no programmer and are still feeling unsure, you might want to visit one of the official or unoffical mozilla communities and ask if someone there with more knowlege can take a look.
